Im not saying dont have goals or desires. Im not saying to ignore if you succeed or fail either- that is important data and part of learning.

To me - Trying my best means looking back to identify things I know I could have done better with more dedication. Could I have done better with the knowledge and tools I had.

>By using the word best there, it becomes yet another goal.

This is kinda the point. Doing your best becomes a goal in of itself. You have 100% control over it and get the satisfaction of meeting it, independent of if you meet your other goals or not. It builds self respect
