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.

If you can dream it, you can do it.

Know or listen to those who know.

Things do not happen. Things are made to happen.

The wise does at once what the fool does at last.

Begin to be now what you will be hereafter.

It's always too early to quit.
