How To Go About Life Knowing You're Doing the Right Thing

The trick to going about life and knowing you're doing the right thing is that you actually DON'T know. No one knows if what they are doing is necessarily "correct", but it may be what is best. There are no certain set of standards in which one should live their life by in order to determine that they are doing it all "right". Just do what is best for YOU, because in the end no one knows what is best for you to do besides you.
