How you can help yourself:
Refrain from taking responsibility for things that go wrong. If it has to, it will.
Try to remember that worrying about something doesn't change things.
Don't force yourself to make every minute meaningful, try to get some sleep.
Give your best, think of it as the perfect. Otherwise there is no perfect, I guess
Cause someone may do it better but it doesn't really matter.
More importantly, to some people you're going to be bad no matter what you do.
It's just okay, you know.
