It's a good idea. If we can turn a hobby into a career, we would get into gear much better. Because it is our place, we could keep the high passion, if not us, who? I appreciate some guys who are working in their fields, never complain about their jobs, and constantly cultivate themselves. In this way, their curiosity would help them develop.
But, we can't deny that sometimes a career will destroy an interest. Because of gain, social pressure around you. Then hobby is not just a hobby but turns out to be money and stuff. So I consider that someone who can insist on their originality, turn their hobby into a career, it is a fantastic choice. Mabey they would be a master in their line of work and achieve their goals.
