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
