After doing programming and being involved in startups for well over a decade, I decided I don't actually like coding nor startups anymore. I still have a company I run with my partners, and I still treat it like my 'job', but there's no passion there. Instead, I've discovered writing novels, music, and other artsy-fartsy stuff as my new passion of the last few years (it had always been a hobby, but I'm taking it much more seriously... not because it'll ever make money, but because I enjoy doing it!)
So my long-winded point is, I don't think there's anything wrong with this. Only you know what your interests are, but don't be afraid to follow them wherever they lead. If you aren't bored, you aren't boring.
The only correct work schedule is the one you are able to work out with your employers and customers which works for you and for them. If those conditions are met it's a legitimate schedule, even if it's only 1 hour a day one day a week.
