or better yet, learn an object-oriented language.
for most of use, learning is a love/hate relationship; we love to learn, but it takes a lot of time and effort which may not pay off as directly as you might like. my advise, focus your learning on a language you want to learn or enjoy learning. otherwise the learning become more of an obstacle than an opportunity. whatever you choose, make sure to actually make the choice. you should be at least playing around with a other languages about every 8 months.
