It's always too early to quit.

If you think you can do it, you can.

Know or listen to those who know.

If you can dream it, you can do it.

To know oneself, one should assert oneself.

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

What you do today can improve all your tomorrows.

Quality is not an act, it is a habit.

I can, therefore I am.
