With respect to your Master's degree query -- it's become pretty useless in my neighborhood. If you're really interested in graduate level work or even teaching, the PhD is your most viable route.
GunLvrPhD's suggestion that you get a professional degree is pretty good... all of such degrees can lead you to a niche where you will be happy (just follow the path of least resistance!), or at least able to afford ammo from week to week!
You may consider interning at various areas, too, in order to see what's out there, and how various career may lead to happiness. Monica had the right idea.
I myself was a french fry technician (tech 1) at McDonald's; where I picked-up many skills that are still with me today. I learned to keep my hands out of my pockets, to always clean things with a Windex-like solution, to clean floors using towels and my feet. I learned how to put potatoes into this big skinning machine (75% skinned), how to cut them in a huge press, how to blanche them in grease, how to deep fry in yet more grease, how to salt, and how to get exactly 4-5 ounces in each french fry bag. I also learned how to say "Yes sir/mam" and then, actually move quickly (unlike the personnel at Mac's today!). This career lasted for several years and paid me enough ($1.85/hr) to put away a sizeable nest egg. Well, it was actually an Easter egg, but to me... wow!
