Romie has great advice!
I have a similar problem with some of my family, in that they always take the defeatist viewpoint. The thing is, that viewpoint has nothing to do with YOU and everything to do with them.
Here's what I mean. After college, I briefly was considering med school (out of the blue; I'd never considered it while in college). When I casually mentioned this to my folks, the first words out of my dad's mouth were "You'd never make it through med school." Thanks, Dad.
Well, I decided for reasons of my own that med school wasn't for me anyway. Now, years later, I have decided to pursue nursing and have been accepted to a direct entry Nurse Practitioner program, which starts in a couple short weeks! I even have a scholarship
! This is all great news! But what does my dad say now every time the subject of nursing school comes up? He says, "Why didn't you go to med school?" ARGH!
His problem is that LIFE IS NEVER RIGHT FOR HIM. Med school wasn't right, but NOT going to med school isn't right, either. This has nothing to do with ME. No matter what choice I make, it will somehow be the wrong one, in his eyes. Not because he doesn't love me or want me to do well, but because of the way he sees the world.
It is hard to learn not to listen to him, since he is my dad and all, and is supposed to be wise (and he is a very smart man). But I figured out that he just doesn't have the right perspective to give me truly helpful advice or counsel about my life. (This is why I didn't tell my parents that I was even considering changing careers to start nursing until after I'd done all my research, made my decision, completed all the applications, and received the acceptances. At that point my mind was made up and no amount of negativity could influence my path. It is still painful to listen to, but I can just roll my eyes now without be burdened by second-guessing myself.)
It sounds like your husband is supportive, and I think he has the right idea! Get a solid foundation in the basics, not just because the info is important, but because of the confidence you'll have going in to the nursing school process (which will be priceless!).
