“Never make a calculation until you know the answer…”

John Archibald Wheeler

Never make a calculation until you know the answer. Make an estimate before every calculation, try a simple physical argument (symmetry! invariance! conservation!) before every derivation, guess the answer to every puzzle. Courage: no one else needs to know what the guess is. Therefore make it quickly, by instinct. A right guess reinforces the instinct. A wrong guess brings the refreshment of surprise. In either case, life as a spacetime expert, however long, is more fun.
