Something that you might want to consider, but which hasn't really shown up in the comments, is... Do you actually _want_ to do the finishing?

Are you taking on these projects because you want the end result to exist, or because you just really enjoy the initial phase of learning and discovering and mapping and planning? If you are getting joy/mental stimulation/a creative outlet from this, then perhaps it is serving its purpose already.

Sometimes, doing something you love, even if you leave it incomplete or do it poorly, is exactly what you need to refresh you. Maybe your hobby isn't building software. Maybe your hobby is just... Dreaming up new projects, and learning about new technology. And if this is your hobby, and not your job, maybe you don't actually need to finish projects at all. Leave the finishing to your day job.
