Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

I can, therefore I am.

Know or listen to those who know.

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

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

The most effective way to do it, is to do it.

Without hard work, nothing grows but weeds.

Expect problems and eat them for breakfast.
