It's always too early to quit.

You never know what motivates you.

Be thine own palace, or the world's thy jail.

The dog that trots about finds a bone.

Go for it now. The future is promised to no one.

Wherever you are - be all there.

Either you run the day or the day runs you.

Things do not happen. Things are made to happen.

Well done is better than well said.
