To know oneself, one should assert oneself.

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

You never know what motivates you.

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

If you think you can do it, you can.

The dog that trots about finds a bone.

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

I can, therefore I am.

Begin to be now what you will be hereafter.
