Ask HN: On how many side-projects you manage to work at the same time?

I’m having a hard time managing my side-projects. I have 3 of them and not enough time to spend to each of them. I’m feeling that I might come up short at all of them. There’s no imposed time schedule, it’s just me pressing myself to deliver.

How do you manage your side-projects? Do you develop different projects at the same time or you focus to one of them until it’s up and running then mess with the other?
