I have a survival world that my younger siblings occasionally join on. I mostly focus on building but do have the occasional small redstone project. I think the main thing that's helped me is accepting that I don't have the time or the discipline do do the things I see other people do online. It might help that I've only been playing for 3 years so there are still a lot of things in the game I haven't done. My inspiration with the game is also driven by the content I consume, mostly Hermitcraft. The important thing is to find the thing you enjoy most. I personally enjoy worldbuilding and making every build with a purpose and story. If you don't have anyone IRL to play with then joining a whitelist server could be something to try. Or maybe a public server with lots of minigames.
