School?

Ok, so I'm thinking of maybe trying to finish up my degree at BYU. I need 8 credits before I can be accepted into the Bachelor of General Studies Program and then I'm not sure of how much or how long it will take. My guess is 3-4 years doing it part time. By then I will be 58-59. Now I am of the mind that education is never a bad thing, but what about the effort and expense as compared to any real monetary benefit in the future. If this were 10 years ago, I would definitely go for it. But, as it is, I really hope to not be working in 3-4 years. It's a quandry.
