I can, therefore I am.

If you're going through hell, keep going.

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

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

You never know what motivates you.

Know or listen to those who know.

The dog that trots about finds a bone.

If you think you can do it, you can.

Begin to be now what you will be hereafter.
