This is what I want to talk about. Does every action have to have a purpose?
If you do that, checking if every action has a purpose, then I can tell you what will happen: you will likely to succeed but you won’t be very happy or satisfied.
Checking if every action has a purpose can make one behave intelligently. But it certainly does not make one amazing.
A genius will never check on purposes. Genius only does what he/she is able to do and be happy with it. There is no purpose.
