I realize how crazy this looks at first glance, but have you considered paying people to work on your side projects for you? I have tried it and it is rewarding.
Why would you pay someone to do something you enjoy doing, so you don't have to do (any/some/all) of it? What kind of side projects are we talking about here?
I’m still glad I did it. It’s okay to farm out the intensive work and savor the fun bits yourself. There are people waiting to do this for cash.
