The dog that trots about finds a bone.
Be gentle to all and stern with yourself.
Either you run the day or the day runs you.
Leap, and the net will appear.
Do not weep do not wax indignant. Understand.
What you do today can improve all your tomorrows.
If you think you can do it, you can.
Problems are not stop signs, they are guidelines.
If you're going through hell, keep going.
If you've got a talent, protect it.
A mathematician is a person who can find analogies between theorems a better mathematician is one who can see analogies between proofs and the best mathematician can notice analogies between theories.
