Success in life is really easy to achieve. We write the rules, we create the 'win' state, we play the game - how can we lose? You would have to set out to lose on purpose by making some insanely silly win state like 'I will succeed when I build a working time machine'.
The tricky part is holding on to the knowledge that we create our own rules. There are lots of other people out there trying to sell the belief that their rules should be our rules. Personally, I don't need a flash new car or big TV or other piece of property to feel like a success. But geez there are so many credit providers who would have me believe otherwise.
