If you can't you must, and if you must you can.

Make today worth remembering.

If you want creative workers, give them enough time to play.

Write it on your heart that every day is the best day in the year.

I believe that if you show people the problems and you show them the solutions they will be moved to act.

You say I started out with practically nothing, but that isn't correct. We all start with all there is, it's how we use it that makes things possible.

Waiting hurts. Forgetting hurts. But not knowing which decision to take is the worst of suffering

For me, I'm focused on what I want to do. I know what I need to do to be a champion, so I'm working on it.
