Certainly having a use case can facilitate the learning process. Project based learning… Also it never hurts to learn! I know enough to be dangerous in many areas LOL…which also means I know when to hire a professional 🤣 But being able to communicate and have a conversation around topics even at a basic level is actually a ginormous people skill. So perhaps frame your efforts in that regard…becoming a better people person by understanding someone else’s domain…THAT could be your project!
