I can, therefore I am.

To know oneself, one should assert oneself.

Problems are not stop signs, they are guidelines.

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

The wise does at once what the fool does at last.

Begin to be now what you will be hereafter.

Without hard work, nothing grows but weeds.

What you do today can improve all your tomorrows.

Know or listen to those who know.
