I recommend the tutorial (Help -> Tutorial) from the menu bar inside Emacs to get you started. Don't listen to people telling you to disable this or that. Use your mouse and arrow keys to get started. Don't worry about what other people are doing with their Emacs too much. Pick one thing you want to do with Emacs and focus purely on that (writing Go, taking notes in Org, etc.) and avoid a wholesale move unless you have infinite time and patience.

My book is of course an option also, but it costs money.
