If you can dream it, you can do it.
Begin to be now what you will be hereafter.
Either you run the day or the day runs you.
I can, therefore I am.
Without hard work, nothing grows but weeds.
Always desire to learn something useful.
Be gentle to all and stern with yourself.
The secret of getting ahead is getting started.
Leap, and the net will appear.
Know or listen to those who know.
If God has made the world a perfect mechanism, He has at least conceded so much to our imperfect intellect that in order to predict little parts of it, we need not solve innumerable differential equations, but can use dice with fair success.
