> I wish someone can mentor me to takes notes and make understand the value of it.

Here's how I look at it. My programming notes have 2 purposes. #1 to keep me on track. #2 for a concrete log of events. I then rewind, playback and observe what and how I was thinking (almost like debugging by reading logs).

#1 helps with focus. I waste way too much time trying new and shiny libraries, reading articles, etc without making progress on the task at hand. If I simply focus on the task, I don't learn new things. This helps me find interesting tools, libs etc. and come back to them later. Also helps to organize important things first.

#2 Helps me find patterns. In the type of work I do, how I approach them, what I was thinking yesterday, how I debugged something 2 months ago. It has made me an overall better, or at least it gave me a feeling that I was getting better. Both are worth the effort.

So when you start, you will either overdo or underdo note taking. Both ends make the resulting notes less useful (usually called "waste"). Getting it right is a matter of knowing which end you are starting, make changes, see results and repeat till you see no improvement.
