I have seen a number of moms sacrifice their family life while going for a new career in college. It is just hard to be there for people when you are doing your own thing. Just because a door is opening doesn't mean it's God. But then again, it might be. This is important. If it were me, I would take a day to fast and pray about it to make sure I'm really hearing from God. If your family is tight on finances, maybe this is a way to alleviate some of that stress. But I'd really think twice about it.
