People think they'll be happy on holiday when they mean relaxed or stimulated or freed from their cares - and indeed they are. Aiming for happiness is one of those 'bigger is best' thing. You're never going to make it because there is no top end limit. You just have to go on aiming for even bigger all the time. Instead of aiming for happy, it's better to aim of contentment. Now that's attainable. That's a worthy goal.
