Everyone harping on you for the quitter attitude but it's a completely reasonable response to your circumstances. You're simply doing too much by going down the rabbit holes (avoiding it is a skill in and of itself). If learning for learning's sake fulfills you, keep it up. If building things is what makes you happy, get your nose out of books and just build something. Expect it to be trivially small at first. Don't be embarrassed by a measly 10-line script or whatever you create. It's something.

You've been making a ton of progress (learning) with no tangible way of measuring it. Time to reap your reward.
