I can, therefore I am.

Either you run the day or the day runs you.

If you're going through hell, keep going.

It's always too early to quit.

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

What you do today can improve all your tomorrows.

Go for it now. The future is promised to no one.

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

Well done is better than well said.
