I can barely finish a leetcode hard in a few hours, let alone something I would call a project. Still, this is an inspiring approach to tackling day to day work in incremental micro-projects.
Personally I find leetcode boring because it's not something that would motivate you to see finished; it doesn't have a "real" purpose, maybe trying to build something concrete (a little game, a little web app, whatever) might bring more motivation.
Everything that’s wrong with interviews, with rent seeking as the cherry on top.
I haven’t tried hard yet but I’m bracing for a shitshow.
