To know oneself, one should assert oneself.

If you think you can do it, you can.

Without hard work, nothing grows but weeds.

If you're going through hell, keep going.

If you can dream it, you can do it.

Know or listen to those who know.

If you've got a talent, protect it.

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

It's always too early to quit.
