What is your favorite idiom proverb or saying?

Hello, my name is Cru. I'm from Argentina. My question is, what is your favorite idiom proverb or saying?

Well, my favorite saying is nothing ventured nothing gained, which means if you don't take any chances or risk, you won't gain anything. So whenever you want to get something in your life, you will have to take action. No matter what people say, no matter your fears, no matter rejection, no matter things getting a little hard, there's no way things will happen just by staying home, laying in your bed. So you have to take things which are risky or which might be hard for you, or you might lost something, but is the only way you can get to your goals.
