It's always too early to quit.

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

Without hard work, nothing grows but weeds.

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

To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

After a storm comes a calm.

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

The dog that trots about finds a bone.
