What is one proverb/idiom that you would say has helped you most in your life?

I just want to know what some of the sayings you’ve heard that have really impacted your life. For me, the two biggest ones have been “don’t trade time for money, trade money for money” and “be where you are.” For the former, I learned that I really don’t enjoy trading work hours for money, when it is much more simple to invest and trade money for money. As for the latter, I have realized that being engaged in my life at the moment is one of the best ways to lead a more interesting life. When I am out, I try to keep my thoughts focused on where I am and who I am with. Let’s hear some of your words of wisdom!
