Here's a kid who's found something he's passionate about and loves what he's doing and all you can do is say "get a life".
We rarely get to pick what we're passionate about. We go through life and, if we're lucky, we stumble upon something that piques our interest. We don't pick when that happens either. You could find your passion when you're 7 or when you're 70, or anywhere in between. It could be technology, cooking, baking, art, music, gardening, exercise, a sport, or any other thing on an endless list.
People who are passionate about something, anything, are the most interesting people to talk to.
