Opinionated Guides is a quite excellent learning resource for various topics ranging from engineering to art, music, and philosophy.
One thing I really like about their Engineering Guide is that the first section is literally about community:
The only way to be successful in this journey is to make friends along the way. Some of this gets really, really difficult. You will get stuck. Having friends to help makes it possible. Find group chats on telegram, join IRC channels, get on some forums, and ask questions on Reddit. Working with people is a lot more fun and you’ll learn so much more.
