I rank money higher than social life or meaning because once you have money, those other things are easier to get. For example, you won't have much of a social life if you can't afford to do anything. And you can't make money if your health is a mess.

Some physicists describe gravity in terms of ten dimensions all curled up. But those aren't real words-just placeholders, used to refer to parts of abstract equations.

There's kind of a toll you have to pay with a cat; if you don't pet her for 10 minutes she'll bother you for six hours.

You don't argue with a four-year old about why he shouldn't eat candy for dinner. You don't punch a mentally handicapped guy even if he punches you first. And you don't argue when a women tells you she's only making 80 cents to your dollar. It's the path of least resistance. You save your energy for more important battles.

People are idiots. Including me. Everyone is an idiot, not just the people with the low SAT scores. The only difference is that we're idiots about different things at different times. No matter how smart you are, you spend much of your day being an idiot.
