Yeah it can be hard. As a self-taught hobbyist I've found a mix of university courses (not whole curriculum, just pick and choose and don't feel bad fast-forwarding over some of the math theory), books (art of electronics, practical electronics for inventors), and high quality youtube channels (eevblog, phil's lab, robert feranec, microtype engineering) to be a good way to learn.

Also eevblog forums are great. I don't post much but just reading through the discussions you get a lot.

My greatest annoyance is the flood of very low quality Arduino tutorials everywhere that polute the search results. Not to be ungrateful, Arduino got me into the hobby, but if you just learned about resistors last week the world doesn't need your blogpost on how to connect it to a breadboard.
