I think a better way to put this is - don't worry about things you can't change. It's my prime directive in life. A big one thing you can't change is "the past". People fret about what could have been different or opportunities they missed, or their childhood being different. But you can't do anything about it. You can learn from it and use that going forward, but you can't wish it was different.
