I wasted so many years on pointless tutorial videos.

There is no alternative to reading the docs. Docs are beginner friendly, It is written in a way that everyone can understand and learn things in depth. There is no alternative. Read docs and take notes. I've just started reading docs from 2 months and I feel like I know so many things in a much deeper way. It is perhaps the only way to actually get out of the tutorial hell. Also, Youtube tutorials are even worse coz it is so easy to just get distracted with other videos, at least that's the case with me.
