IGotThis provided some amazing examples of things that you can use and the different kinds of levels/intensity of the activities. For example, if you were interested in writing you could have different types of activities that involved writing and creativity in that area as well as a few more general ones for the times you don't want to write.
From there, it is just trial and error. Seeing which ones work for you when you are struggling and which don't.
If you can think of a few of your interests we are more than happy to try and help you come up with some more ideas
