It's always too early to quit.

If you think you can do it, you can.

The secret of getting ahead is getting started.

The most effective way to do it, is to do it.

If you're going through hell, keep going.

Without hard work, nothing grows but weeds.

Well done is better than well said.

If you've got a talent, protect it.

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