Without this ridiculous vanity that takes the form of self-display, and is part of everything and everyone, we would see nothing, and nothing would exist. – Antonio Porchia, Voces, 1943, translated from Spanish by W.S. Merwin
If you imagine someone with 100 percent determination and 100 percent intelligence, you can discard a lot of intelligence before they stop succeeding. But if you start discarding determination, you very quickly get an ineffectual and perpetual grad student. – Paul Graham
