We don't inherit the earth from our ancestors; we borrow it from our children.
The person who tries to live alone will not succeed as a human being. His heart withers if it does not answer another heart. His mind shrinks away if he hears only the echoes of his own thoughts and finds no other inspiration.
Dream big, work hard, and stay humble.
I don't think you can ever stop learning. There's always something new to discover.
