I can, therefore I am.

The dog that trots about finds a bone.

To know oneself, one should assert oneself.

What you do today can improve all your tomorrows.

If you're going through hell, keep going.

If you think you can do it, you can.

Expect problems and eat them for breakfast.

If you can dream it, you can do it.

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