Oh man, the days of getting burnt-out come often too! Sometimes you just need to pull back and find another hobby to keep your mind occupied. Seriously, your deep knowledge of Python or Javascript will grow over time as you get real experience with it, not from reading tons of articles that will never apply to circumstances that you'll never be a part of. You'll gain more knowledge from experience, so take a step back and enjoy life before those experiences come, and you're to burnt out to take them on.
