I have cleared some of the toughest entrance tests in the country like that for IIT, IIM, IAS. It is not that I was not distracted during studies, but I overcame those distractions.

Small tips on how to overcome distractions and get great focus

A thread🧵

Reducing mobile usage

👉 Measure

Check your phone usage and apps u spent time on every week. Many times you dont even know how much time you are wasting on mobile apps. Android users can use free apps like

Steps to reduce usage

👉 Physical distance
Keep the phone with the internet switched off and away from you while studying. You can also keep it locked and with a parent/ friend. Heavens will not fall while you are studying and if it is something urgent, you will get the message.

👉 Technological solution:

Use apps like Blackout to block internet for at least 6 hours every day. Force yourself to study in that time. It is not a free app, but it is very effective. Once it blacks out the phone, you can't go back for the period

👉 Early morning study

Keep the alarm away from you, on loud volume. Most likely once you get up from the bed to switch off the alarm, you will decide to not go back to sleep and study. Early morning study is the best these days especially as it has lesser distractions

You may like to read reviews online before opening an account with any provider.

Is there a statutory limit on investment?

As Indian resident, RBI’s Liberalized Remittance Scheme lets you remit upto $250,000 per year, per person. Above that, permission from RBI is required.

What are the capital gains tax on foreign stocks?

- US doesn't tax capital gains for us. However, tax applicable in India.

LTCG:- applicable if held above 24 months. Taxed @20% with indexation benefit
STCG:- if held for less than 24 months, Taxed at your income tax slab rate

What is the tax on dividends earned?

- Dividends taxed at flat 25% in US
- Also taxable at your income tax slab rate in India
- As per Double Tax Avoidance Agreement, tax withheld in US offsets tax liability in India

So tax to you is 25% or your tax rate, which ever is higher

I have made powerpoint presentations in front of Hon'ble Prime Minister, Chief Minister, Cabinet Secretary and top bosses of MNCs. By God's grace, they were always received well.

Some tips for making effective presentations along with tech tools.

A 🧵. Pls RT for wider reach

Know your audience

A presentation in front of Prime Minister would not be the same as that infront of your technical team. Even if the topic is the same. Understand the audience and know what they need from the presentation. Plan accordingly

Structure

Some people naturally think in a very coherent way. If you are not one of those, make an outline of the presentation first. Try to get the flow right.

Problem-Solution kind of presentation

State the problem and then tell what you did to solve it. (or going to do)
The 'how' you achieved it should follow after that. This gives more impact

Slides

Make concise slides with few words. The slides should just be cues for you and your audience. Dont put all details in them. Just a few phrases/lines should sufice

Making the right decision at the right time is critical to success in life.

Here are 4 decision models used by 4 stalwarts - Jeff Bezos, Charlie Munger, Elon Musk and former US president Eisenhower.

A thread 🧵

1. Reversibility - Used by Jeff Bezos

Categorizes decisions based on whether they are reversible or irreversible

👉 Reversible - 2 way door: Can go back from decision with less/no cost
👉 Irreversible - 1 way door: If enter once, can't exit (Or the cost is very high)

👉 Reversible: decide quickly without perfect process. Dont take much time.
(This is not to be reckless though)

👉 Irreversible: Decide slowly and take as much information into account as possible

When Bezos was deciding to leave his job at DE Shaw to start Amazon, he thought that he could come back to job if Amazon doesn't work. So it was a reversible decision.

He decided to launch Amazon quickly. He got the first mover advantage and the rest is history!

2. Inversion - Charlie Munger

Instead of thinking what would make you successful, first see what would make you fail. Then remove those things.

If you are following a goal, first see what can kill it for you. Avoid that.

👉 Avoiding stupidity comes before seeking Brilliance

How to create a freelancing website that makes money.

Everything I've learned.

A thread.

As a freelancer,

Your website is everything.

First, prioritise its existence.

Second, prioritise its improvement.

The technology you use is irrelevant.

- WordPress
- Notion
- Carrd
- Wix

It doesn't matter which you choose,

What matters is you have a website.

Pick a platform that you're comfortable with.

If you can:

- Capture leads
- Add content easily
- Have a clear design

You're good.

If your website doesn't get leads,

It's not working.

Don't rest on a website that doesn't work for you.

Improve it until it does.

THE BATTLE OF PRATAPGARH (10 Nov, 1659)

Chhatrapati Shivaji Maharaj's impeccable military genius and matchless courage humbled the Adil Shahi Sultanate.

The beginning of what was to come later for the M0ghuls from one of the most indefatigable defenders of Dharma!

(Thread)

Shivaji’s growing influence in Maval region, made him a threat to the Adil Shahi ruler of Bijapur who sought to restrain him. The man who was given the responsibility of this mission, was their commander, Afzal Khan. Afzal was a formidable warrior known for his ruthlessness.(1)

His strategy was to bring Shivaji out into the plains, where he held an advantage, compared to the rocky Deccan terrain. Afzal attacked the holy town of Pandharpur, and later demolished the temple of Bhavani at Tuljapur to instigate Shivaji in a bid to bring him out.(2)

Shivaji was angry but remained patient. Knowing that he could not defeat Bijapuri Sultanate in an open battle, Shivaji moved to Pratapgarh fort, located on rocky heights, surrounded by thick forests of Jawali.(3)

This set the pattern for future Maratha attacks, using guerrilla warfare against larger invading armies rendering them ineffective in unfavorable terrain.(4)

1/x Fort Detrick History
Mr. Patrick, one of the chief scientists at the Army Biological Warfare Laboratories at Fort Detrick in Frederick, Md., held five classified US patents for the process of weaponizing anthrax.

2/x
Under Mr. Patrick’s direction, scientists at Fort Detrick developed a tularemia agent that, if disseminated by airplane, could cause casualties & sickness over 1000s mi². In a 10,000 mi² range, it had 90% casualty rate & 50% fatality rate

3/x His team explored Q fever, plague, & Venezuelan equine encephalitis, testing more than 20 anthrax strains to discern most lethal variety. Fort Detrick scientists used aerosol spray systems inside fountain pens, walking sticks, light bulbs, & even in 1953 Mercury exhaust pipes

5/x Back in Time
In 1949 the Army created a small team of chemists at "Camp Detrick" called Special Operations Division. Its assignment was to find military uses for toxic bacteria. The coercive use of toxins was a new field, which fascinated Allen Dulles, later head of the CIA

THE EVOLUTION OF OUR NATIONAL FLAG (1857-1947)

The INDIAN NATIONAL FLAG is not just a flag! It's a testimony of patriotism and seamless sacrifice. A symbol representing one of the oldest civilizations on this planet.

Let's hope what happened yesterday never repeats!

(Thread)

After the revolt of 1857, the first Indian flag was designed. The design was based on western heraldic standards with "Union Jack" in the upper-left quadrant and a "Star of India" enclosed in the royal crown in the middle of the right half.(1)

The flag was a symbol of the direct imperial rule in India.(2)

In 1904 the first Indian flag which stood for India's independence from the British was devised. The design was provided by sister Nivedita, an Irish disciple of Swami Vivekananda.(3)

The flag was red and yellow with an image 'Vajra' (weapon of god Indra). The phrase 'Vande Mataram' was written in Bengali on it. The red colour and the yellow colour signified freedom and victory while the symbol of vajra stood for strength.(4)

1. There are more people added on the list of arrests and executions of famous people but no further intel is available at this time.

ARRESTS and EXECUTIONS OF FAMOUS PEOPLE 2020 UPDATED
Explanation of the latest military tribunal arrests and executions of famous people in 2020.

2. The tribunals are arresting these people in plain clothes. We saw the Obama’s arrest, although we didn’t know it was an arrest at the time. The arrest was done nonchalantly so as to not get noticed by the public.
All arrests of these famous people were done this way.

3. If the person is convicted of child sex trafficking, crimes against humanity or treason, they will be executed.
If the person arrested has evidence on someone else to help their prosecution, or is willing to help Trump, & they want to cooperate, they may be allowed to do so.

4. A sentence of execution down to life in prison may be accepted if their evidence is worth anything.
When a plea deal is done, the defendant must present evidence they have to make their sentence lighter. This information is given to the prosecution, defense, and to the judge.

5. If evidence is accepted, they are presented the plea deal. They will have to make a guilty plea to the crime with a video confession & written statement. That is how all plea deals work.

All famous people arrested were either treasonous or involved in satanic worship rituals.
