Stuck in the "I don’t know" for Goal

I have always wanted to work from home and be self employed or have little supervision. It is something I never even dream about anymore because it seems so far off. This year I wanted to pursue it. The only problem is I don’t know what I would be doing? My current career is a Manager in Information Technology. I love helping people and I love fitness. Those are both my passions. How do I find my purpose or come up with something that I could do to allow the flexibility to work from home or make my own hours but still keep a decent income? I am stuck in the I don’t know what I need to do to get this dream!
