I think in terms of his descriptions of our responses to choice and decision-making, I'm mostly a 'satisficer' rather than a 'maximizer' -- I've often noticed I'm very good at finding 'good enough' and pretty much never have buyer's regrets. If you are troubled by past choices very often, give this book a read (despite the opportunity costs of taking the time to read it ;-).
