Learning a programming language is stretching your skills, as a developer. It’s a new tool in your toolbox, too. With it, you can create something out of thin air. If you’re lucky, others will find your creation useful, and you’ll feel the warmth of being helpful. Beyond that, I love programming by itself: it’s a game to me. Logic is really fun to mess with. Learning is fun too: the excitement of discovery, the joy to finally understand a hard concept.
