I can, therefore I am.
The wise does at once what the fool does at last.
Know or listen to those who know.
The secret of getting ahead is getting started.
The most effective way to do it, is to do it.
If you've got a talent, protect it.
Begin to be now what you will be hereafter.
The dog that trots about finds a bone.
Well done is better than well said.
To know oneself, one should assert oneself.
But I don't think we'll go there until we go back to the moon and develop a technology base for living and working and transporting ourselves through space.
