A hero is no braver than an ordinary man, but he is braver five minutes longer.

I think, therefore I am.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

It is never too late to turn an unproductive day into a productive one.
