That line about "I can actually read my own code" really hits home for me. I had the same thing happen when I tried JS first and spent more time hunting missing semicolons than actually learning how to think through a problem. Python letting you just write a thought and run it is huge when you are starting out, because you stay in the flow instead of getting yanked out by punctuation junk. Your buddy means well but "make websites right away" is a trap, you end up copying code you don't really get. Sticking with Python was smart, and honestly the ideas you learn there carry over fine whenever you do pick up JS later. Three months in and reading your own code is a real win, keep at it.

Check your basement rim joists next, that's where old houses leak the worst and foam board plus spray foam is still a cheap fix. Also feel around your outlets on outside walls, those little foam pads behind the covers are like a buck each and stopped a draft I never noticed. Old houses are basically a bunch of tiny holes wearing a roof, so walk around with a candle on a windy day and you'll find your next $8 win lol.
