Only other thing I'll say is that before getting into QF it was all about trying to make the next step as soon as possible, always rushing to take the next promotion, bigger a/c etc. Once you're 'in' many find the thinking changes a little. Lifestyle becomes an important factor, you work to live, not live to work.
