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

It's always too early to quit.

To know oneself, one should assert oneself.

To be a good loser is to learn how to win.

Things do not happen. Things are made to happen.

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

You never know what motivates you.

I can, therefore I am.

Know or listen to those who know.
