I try to stick to one main project (https://issueembed.dev/) but do allow myself to indulge in one or two other ones when I need a break.
I also try to have my environment setup automated and some level of testing so that if I do switch between projects, I am not wasting time on regression or environment setup. This may be best practice but it is very easy to not bother with in a side project.
It used to be a free for all and I'd have a lot of different projects working on at different stages but I'd rarely finish anything or get it to a stage I was happy with. I now just track any other ideas I have in a Trello board and look at it occasionally to get inspiration.
