I got real estate license as it seems to combine my love for exploring new areas, meeting people, and freedom to set your own schedule. But I could not go full-time into it as I have kids and didn't want to be away showing homes on weekends or in the evenings.
Other times I tried to do part-time portrait photoshoots as you get to be outside. But again as a father, I didn't think it was worth it. But you can make decent income with just outdoors family portraits.
I feel a little sad about not pursuing these a bit more. But I am taking my kids outside as much as possible, getting them into photo- & video-graphy, and just having fun. This seems to make me not only happy but also more motivated at the work. Perhaps, you can pursue some outdoors hobbies before making any big moves.
