“As you grow older, you'll find the only things you regret are the things you didn't do.”
“Always regret the things you did do, never the things you didn't.”
“Only regret the things you don't do”
“You'll find that the only thing you can do easily is be wrong, and that's hardly worth the effort.”
“The only things I regret, and the only things I'll ever regret are things I didn't do. In the end, that's what we mourn. The paths we didn't take. The people we didn't touch.”
“What you'll find, I think, is that the things you most want to avoid are the things that make you feel the greatest when you actually do them.”
