It's always too early to quit.

To know oneself, one should assert oneself.

By failing to prepare, you are preparing to fail.

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.

I can, therefore I am.

Either you run the day or the day runs you.

If you're going through hell, keep going.
