Enable your future self to learn from your past self - because your future self will forget everything

We often think of ourselves, that we remember things but we have a natural built-in function to forget. It's in our nature to be forgetful of the not so important things – but also important things slip through.

So whenever you read something and think, "I should remember this" or "This is interesting, I should do something with it" you should always write it down!

This will help your future-self, even though your current-self thinks, that it's not important to write something down or setup a reminder for something.

Your mind is for having ideas, not holding them said David Allen, inventor of GTD. So you should take notes about things you want to remember while keeping in mind that In your personal knowledge management system, everything should be high quality and trusted knowledge.
