“Have no fear of perfection. You’ll never reach it.” – Salvador Dali
Perfectionism is a trap. It does not exist.
At best, you can attempt to do good (according to whatever standard you hold).
Additionally, even if you do exceptional work, life is not a fair grader. For example, you could be the nicest person in the universe. However, someone may not like you because they value drama, negativity, and complaining.
Do not try to be perfect. 70% or 80% is OK. You will make mistakes, but you (probably) won’t die.
