I'm actually highly considering going into this myself - not because I am busy...but after experience I have found that while attending classes..I tend to get bored easily..therefore not paying attention..but when taking a few classes offered online I;ve done much better in subjects I did horrible in before..

But I think that if a person is capable of settign a schedule for themselves and sticking to it..and are able to pick up things on their own...then I'd tell them to try it out. Its a great opportunity to become committed to furthering their education..and still stick to their job.
