“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.
