I was kinda similar when I first started using it. I watched heaps of videos and had so many plugins installed but I was never really sure if I was doing it "right". Then one day I got annoyed and uninstalled every plugin and just went back to basics. I only reach for plugins when I feel something is missing, but honestly the only plugins I use are Style Settings which let's me customize the theme a bit more and Calendar so I can have... well... a calendar.

I think the real power of it is the fact you can extend as much, or as little as you want!

Linter and Templater are the two I can't live without. The rest are just nice to have.
