The proof is by reductio ad absurdum, and reductio ad absurdum, which Euclid loved so much, is one of a mathematician’s finest weapons. It is a far finer gambit than any chess gambit: a chess player may offer the sacrifice of a pawn or even a piece, but a mathematician offers the game. -- G. H. Hardy

A charlatan makes obscure what is clear; a thinker makes clear what is obscure. -- Hugh Kingsmill

Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live. -- Martin Golding

In OO, it's the data that is the "important" thing: you define the class which contains member data, and only incidentally contains code for manipulating the object. In FP, it's the code that's important: you define a function which contains code for working with the data, and only incidentally define what the data is. -- almkgor, on reddit

I think it is wise, and only honest, to warn you that my goal is immodest. It is not my purpose to "transfer knowledge" to you that, subsequently, you can forget again. My purpose is no less than to effectuate in each of you a noticeable, irreversable change. I want you to gain, for the rest of your lives, the insight that beautiful proofs are not "found" by trial anf error but are the result of a consciously applied design discipline. I want you to raise your quality standards. I mean, if 10 years from now, when you are doing something quick and dirty, you suddenly visualize that I am looking over your shoulders and say to yourself "Dijkstra would not have liked this", well, that would be enough immortality for me. -- E. W. Dijkstra

If you can’t explain it simply, you don’t understand it well enough. ~Albert Einstein

When I was 5 years old, my mother always told me that happiness was the key to life. When I went to school, they asked me what I wanted to be when I grew up. I wrote down ‘happy’. They told me I didn’t understand the assignment, and I told them they didn’t understand life. –John Lennon

Nothing in the world is more common than unsuccessful people with talent. ~Anonymous

Take up one idea. Make that one idea your life - think of it, dream of it, live on that idea. Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the way to success. ~Swami Vivekananda
