The problem isn't in having multiple interests, it's in how you organize them.
Creating an organized system that at its default allocates the time to each interest/task according to priority and maintains high output even in low inputs is what you should go for.
Organization folders for interests -
1. The money maker - Contains skills and tasks that pay the bills, generate leverage and provide for other interests. Top priority.
2. The soul stuff - Contains the interests/tasks that make you feel alive, worth. Second on the priority list.
3. The curiosity stuff - Contains interests that you want to do/explore. Like learning, reading, exploring things, activities and subjects that are important to curiosity but not just now. Tasks can be distributed among the life timeline. Areas of exploration in simple words. Third on the priority list.
Try to create an intersection between all three and create a life stuff folder that contains tasks that can be curiosity driven, soul satisfying and money makers.
