Without knowledge, action is useless, and knowledge without action is futile.

Happiness is not something ready-made. It comes from your own actions.

Just because something doesn't do what you planned it to do doesn't mean it's useless.

He who is not every day conquering some fear has not learned the secret of life.

A champion is someone who gets up when he can't.

Knowledge will give you power, but character respect.

I try to learn from the past, but I plan for the future by focusing on the present exclusively. That's where the fun is

The past always looks better than it was. It's only pleasant because it isn't here.

The end of all knowledge should be service to others.

The science of today is the technology of tomorrow.
