My First (the oldest) doesn't really know where/what she wants to do/be and if that doesn't change before her 18th birthday - I will suggest to her what her Mama thinks would suit her, and that would be to get a degree in library sci; that kid has a real abiding passion for stories and lit, especially children's stories, and libraries completely excite her and are her second home all at the same time. She may not get rich off of it, but she will be happy at work and it won't be flipping burgers. We'll see how far she gets before the money-crunch hits.
My Second has been definite for years now, we will see if that lasts until she turns 18. Fourth is only nine...
I'm normally not into telling my kids what they should be (but I do tell them that they need to have SOMETHING decently solid on which to build, and as long as it is legal, moral, ethical, and pays their personal bills after graduation/completion/whatever, I will be okay with it) but I will push a bit if they are aimless post-18 (which I don't see happening, I'm just sayin').
Hubby is doing well with his chem degree (allows me to be a SAHM). My brother did the JVS/trade school thing, became a machinist, and now is in management at his company and doing well. I have no degree, just a whole lotta' life experience, so if Hubby dropped dead, I would have to study - which doesn't bother me per se (as I intend to when the kids are on solid footing), it would just be a real adjustment. However, I don't like this feeling I have of not having that "something" that I am preaching to my girls about... actually - it is the reason I tell them that, especially as they ARE girls.
Life lesson on my part.
