The underlying problem isn't with Minecraft, but how you approach it. You do nothing but build/do stuff per some checklist of things, and probably get most of your designs from youtubers (ie, MumboJumbo, TangoTek, ImpulseSV, etc). Basically, you haven't really done anything creative and in a game that's 99% creative you are extremely missing the point.
This is exactly what I started to do Copy/Paste others ideas and it get's boring fast!
When I started my own survival world off using my username as my seed I have built everything from my own imagination And It's been a joy to play ever since.
The only thing I check others builds out for now is because I suck at redstone and mechanisms So I do need a little help sometimes. And a little inspiration from others is a good thing as long as it's not a copy/paste situation again!
