It's always too early to quit.

The dog that trots about finds a bone.

The secret of getting ahead is getting started.

To know oneself, one should assert oneself.

What you do today can improve all your tomorrows.

Problems are not stop signs, they are guidelines.

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

Either you run the day or the day runs you.

Well done is better than well said.
