To know oneself, one should assert oneself.
Begin to be now what you will be hereafter.
The secret of getting ahead is getting started.
Go for it now. The future is promised to no one.
Without hard work, nothing grows but weeds.
Who seeks shall find.
Be gentle to all and stern with yourself.
If you've got a talent, protect it.
The wise does at once what the fool does at last.
Always desire to learn something useful.
Why fear death? It is the most beautiful adventure in life.
When you consider all the stars I have managed, mere submarines make me smile.
