Writing is difficult. I think it takes a certain gusto to do it. I think paired with the daily life of having to do it affects a lot of people, maybe more than they let on. I think I'm the same.
The pressure of writing something considered "good" is immense, except when it isn't. In my opinion, I think we're in a really odd time, specifically for writing. I think that it's amplified that artists are notorious for either being incredibly doubtful and pessimistic about their work or being complete egomaniacs. It's pretty funny how little "in the middle" artists I interact with. I've had interactions with people who believe their very first and only project will be their magnum opus and I've met people who refuse to work on a project in fear of messing it up. In all honesty, I'm sure I've been both at some point in my life.
Do I think the terrarium that I've made is the best one that I'll ever make? No, not by a long shot. But I don't think it's half bad. I've learned a lot from it (and that I can paint minifigures fairly well apparently), so I'm not against making a new one, maybe a larger one. It's surprising, but Facebook Marketplace is constantly full of old aquariums for cheap that need a home, and I think the next one I build I'd like to make will have more foliage and less plants that are taller. I was really focused on the fountain being an integral part of the terrarium, and while it is, I think maybe making a fountain from scratch with aquarium foam sounds incredibly challenging and even more fun.
I've also learned a lot about myself, frankly. Not in a "I am surprised by the consequences of my life" way, but in a "hey, I can actually do a hobby!" way.
