I can, therefore I am.

Be gentle to all and stern with yourself.

If you think you can do it, you can.

Without hard work, nothing grows but weeds.

The dog that trots about finds a bone.

To know oneself, one should assert oneself.

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

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

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