What about a B2C app that solves a real problem for real users in a new or better way than existing apps? That seems like an easy way you can deliver real value. That's what's gotten me moving on all my personal projects so far—though granted, I haven't published/monetized them yet, just shared them with friends and family. But I get value from them and my friends and family get value from them, and that makes me feel good.
Value to someone, sure. I wouldn't necessarily see the value in it.
I do have personal projects, one to do good, others out of curiosity. Mostly out of an urgency to be creative. I don't think this carries more meaning than pure leisure.
