@ayoAyo! I don't know that I've met many people who think of hobby projects as something used in serious business. A few, to be sure. And sometimes you're Linus Torvalds and your hobby is trying to recreate UNIX from first-principles.
... but it is 1,000% okay to have a hobby be something you do, for you, for fun, to unwind. Something you could just as easily throw in the trash as show the world.
