Anyone here got out of consulting/corporate life and done something they care about?

I am lucky to have a role within consulting that is somewhat interesting and around cutting edge tech. But. I hate it. I want more freedom and flexibility and I want to work with people I like. Projects I find meaningful etc. My dream would be to open my own gym and coach athletes. But the money around that in the UK is dire.

Has anyone here succesfully managed to do something like this?
