I say go for it. I have taken classes in my teens, mid 20's and early 30's, it definitely gets easier the older you get. You tend to become more focused when your older, and more importantly you have a better idea why your taking these classes, and enjoy the knowledge a little more. The cost is crazy, but there are many programs for non-traditional students. The hardest thing was balancing a full time job and a few classes, but it is definitely manageable with some planning. Best of luck to you.
