If you think you can do it, you can.

The dog that trots about finds a bone.

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

To know oneself, one should assert oneself.

The secret of getting ahead is getting started.

If you can dream it, you can do it.

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

It's always too early to quit.

Things do not happen. Things are made to happen.
