Nishant says: 2x Output for 1x input...

His formula for mastery: 1. Learn (input -- focus, singletasking) 2. Reflect (output, pause... what is the main takeaway, how to use?) 3. Implement (output, apply) 4. Share (output, teach the material)

These principles are great... Obviously they are not comprehensive as they do not necessarily reflect higher order learning. See Bloom's and Solo's, nor take foundation of Cognitive Load Theory for example... It's understandable though since you can't mention everything in a 20 minute talk XD.

The argument I'd make is that the 3 subsequent steps are a part of learning. So the first step should not be called learn but rather encode, since that is literally the process of forming the initial cognitive schemas and putting them into long-term memory...

According to Nishant, what I agree with, the truly successful people are MASTERS in their craft. They have committed to lifelong learning.

"Your learning capability decides your earning capacity."

See also: Ultralearning, Scott H. Young, and Deep Work, Cal Newport... The argument is the same: your ability to adapt in a complex rapidly changing information economy, and to master material determines how much you can earn.

Nishant Kasibhatla memorizes a 30 digit "random" number at the beginning of the video and recalls it correctly, in reverse, at the end of the video.

He uses number visualization of combinations to do this. (every 2 digit number has an image in his mind that he has practiced substantially in relation)... Similar to Mind Palace.

He did make a few mistakes in the normal recall at the beginning... But it is safe to assume that he did it on purpose (for what reason I do not know), because he has a lot of expertise in it.
