Which career would you rather choose?

One is your dream job, but demands a degree that is hard to get accepted into, demands licensing, is harder to find a job as, but with experience you can have more control over and even be your own boss, but that's less secure, pays worse in the beginning but ends up being similar to the other one. The other one demands a degree that is less specified and easier to get into, easier to find a job as, more diverse work environment but you can never be your own boss, pays well, even from the start, but it's not really what your heart desires, although you could imagine to settle with doing that. Would you let your heart decide and choose the more exciting but less secure or folliw your head and choose the more boring but better paid?
