We already know, man. You're posting in the "Off Topic" section of the website.
From what your options sound like, it doesn't sound like you're going to find any purpose in life from your job alone. "Wow, my life is so much better now that I trade stocks instead of finding people mortgages!" That doesn't sound right, does it? Why not use the money you get from whichever source of revenue you choose as an avenue for a passion? Finding that passion, hobby, pursuit, or whatever else you'd like to call it is, of course, going to be a lot more difficult of a task, but from what your words sound like, it seems like you're under the conviction that a job alone could give you the purpose you lack, which I doubt is the case for most people.
