I'm a nerd re: productivity systems, so here's a thread of some books and things that helped me this year, and might be helpful for some of you making New Year's resolutions:

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)

DETAILED VIEW- Running commentary

1. Chhatrapati Shivaji chose Pantaji as a lawyer to communicate with Afzal Khan. Pantaji was very sharp minded, who did his job very nicely.

2. He presented Chhatrapati Shivaji is fearing Afzal Khan and he wanted to invite him in his kingdom near Pratapgad.

3. Pantaji succeed in the communication with Afzal Khan and he brought him as per the planning of Chhatrapati Shivaji.

1/ Here are my notes from @robertwrighter's book - Nonzero: the logic of human destiny. I enjoyed the book very much.

The basic premise of the book is that history has a direction which favors co-operation and non-zero sum games, and that causes an increase in complexity.

2/ Starting from the first replicating molecule which co-operated with an outer layer to form first proto-cell, evolutionary and cultural history is full of examples where two entities come together to survive and progress a lot more than they would have done individually.

3/ This co-operative entity fares much better than two individual entities because of specialization. If two entities are in the same boat - that they win together or lose together - then trust is implicit.

4/ In a non-zero sum game, trust causes entities to focus on what they do best.

For example, eukaryotic cells - the ones animals and plants have - emerged when two proto-cells merged, and one took the role of energy generator (mitochondria), the other specialized in protection.

5/ Some scientists believe that even nucleus in a cell is a result of an early cell merging with another cell.

So M&A is not a recent phenomena, entities have been merging because of common interests ever since life started.

Published a new essay: The red flags and magic numbers that investors look for in your startup’s metrics – 80 slide deck included!

This was a deck that I created on my (longish) interview process with @a16z. It was a long path, starting with meeting folks at the firm 10 years ago. But the purpose of the deck was to explain how I would use my superpower in an investing context

Here's what I explain in the deck. As investors (whether angel or VC) we're often confronted with an up-and-to-the-right graph. Is it going to go up? Or down?

One solution to forecast these growth curves is the Growth Accounting Framework, where you add up New+Reactivated and subtract churned users. In each time period that gives you the difference in monthly actives.

The problem with this is that it's a lagging metric, not a leading one. We need to go one level deeper and look at the underlying loops that drive these numbers, to understand the quality.
