this is something I've been trying to understand for a while
What does it mean to "do your best"?
Are you legitimately always trying to do your best, or are you often titrating your effort based on your internal reserves?
What does "your best" mean to you?
chemist word
seems stressful to attempt 'your best' at things, so often in the completion of a task you learn or find a better way so your 'best' now has a higher standard and then you should redo or continue instead of turning in a finished thing. 'best that can be expected' is a better calibration because you'd better believe the amount of care, time, and effort is contingent on who it's for, and conditions.
