Why Build Toys
I'm not sure about you, but the more experienced I am, as a developer or "builder", the smaller things I end up making.For instance, I launched a bunch of games that are, frankly, more fun to watch, than to play (e.g. an All-hands meeting simulator: https://rafsters.itch.io/all-hands) or 
little tools this one https://sonnet.io/posts/reactive-hole/ (it's stupid, completely replaceable, but somewhat adorable).I come from a family with 4 generations of carpenters. It's a profession more similar to software engineering that most engineering jobs I can think of. The main difference is that in our domain so often the results of our work just don't feel real.If you're in this situation and this frustrates you, either build something small that people would use OR go ahead build something useless, but intentionally.
