For myself, in my late fifties, I'd say that it's too late to do all the things that I'm interested in, that I'd like to do, but that don't really hold my attention enough to get going in.<p>Learning to program is one of those things. Always been fascinated by it, always wanted to do it, but every time I've made a stab at it, it doesn't hold my interest.<p>But for the last five years I've been learning Chinese. Something that I NEVER had the slightest interest in doing (until I started) and never would have believed that I could do. But for some stupid reason, I work at it every day, 365 days of the year and I like it, even though my progress has been painfully slow.<p>I'm not sure what the moral of this story is. Maybe just that you might as well do what you love, no matter what age. And also, that you might not know what exactly you really love until you try it.
