To know oneself, one should assert oneself.

It's always too early to quit.

The secret of getting ahead is getting started.

Quality is not an act, it is a habit.

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

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

If you're going through hell, keep going.

Either you run the day or the day runs you.

What you do today can improve all your tomorrows.
