I want this to be true, but I don't think it is. I really do think a lot of people just kind of drift through life, being reactive rather than proactive, with little in the way of goals or ambition. I don't necessarily know if there's anything wrong with that (topic for another day), but it does seem valid to say that they're not interested in "improving". Maybe that's the wrong word; maybe "optimizing" captures it better. Regardless, some of my best friends are those who I share surprisingly little in terms of common interests. But what we do share is that we don't want a life adrift, and we're working hard to achieve the things we care about. To me, that's what "improving at life" means.
