To know oneself, one should assert oneself.

It's always too early to quit.

I can, therefore I am.

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

Without hard work, nothing grows but weeds.

Leap, and the net will appear.

Problems are not stop signs, they are guidelines.

Quality is not an act, it is a habit.

Begin to be now what you will be hereafter.
