한계 - Limits

Sometimes I feel like I'm an invincible superman. Like I can do anything.
That situation is rare, but I've had that experience.
Usually I'm a little annoyed at the things I'm not able to do.
In English you would call me a perfectionist. I found the word "완벽주의자" in a Korean dictionary. Is that right?)
Of course it's good to do your best in everything you do but there are limits.
Whenever I forget that limits exist I read the following quote:
"Do what you can, with what you have, where you are" Theodore Roosevelt.
"어디든지 가는지, 무엇 가지고 있는지, 할 만큼만 일을 하세요." - 시어도어 루스벨트
I sometimes forget that I am not Superman. Limits are important.
You can't do anything above your limits. Working below your limits is no good. That's lazy.
Situations in life are not always perfect. I have to believe in that.
Everybody, do you have any good proverbs for frustrating situations?
If so, let me know.
