If you're going through hell, keep going.

Either you run the day or the day runs you.

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

It's always too early to quit.

I can, therefore I am.

Know or listen to those who know.

If you think you can do it, you can.

By failing to prepare, you are preparing to fail.

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