I'm new to minecraft and I can't think of anything easy but fun to build what should I build?

I got minecraft about a year ago but I can't think of anything easy to build and i have tried survival mode but I'm terrible at it so I need something easy to build but it also needs to be fun.

Make pixelart. Like a giant Mario. It's actually really easy if you have image reference.

Build a pool!

Build a small town or city
i like to build several monuments around an area (lighthouse, dock, treehouse, etc.) and the create a kind of train station connecting all of the monuments.
create a farm with animals and crops

Play with mods like Pixelmon or adventure maps.
