Hobbies are almost by definition not mandatory activities. Earning money to eat and pay the mortgage is not really optional. Making the hobby activity mandatory will make it feel a lot more like work and a lot less like a "fun" activity. It might not be as bad as working in an Amazon warehouse, but it'll be a job all the same. Worst case, if you get burned out on the new job you will not only no longer have a job but also won't enjoy your hobby anymore.
