I can, therefore I am.

If you think you can do it, you can.

Be thine own palace, or the world's thy jail.

Expect problems and eat them for breakfast.

The dog that trots about finds a bone.

It's always too early to quit.

Know or listen to those who know.

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

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