This is an interesting problem. Here is a potential solution that I (roughly) follow when I’m not very busy.

Start with a group of interests that has the most overlaps in terms of skills or resources needed - call these compounded projects. Out of the compounded projects, start with the one that interests you with 2 weeks of effort. If you can’t make a significant progress in that time frame, you either lack the skills, resource, or interests in them. Move onto the next compounded project.

After you finish with the list of compounded projects, review the original list and prioritize the interests based on your experience. Create compounded projects again and go at it. Repeat.
