Work, school, husband, and baby, How do you do it?

I am 21 Married to soldier, in nursing school part time and working part time in a hospital but have no children. I THINK about having a baby ALL the time. My husband and I have been married for over a year. And he will be coming home in a week (very excited). I am on BC (ortho tri-cyclen lo). I would like opinions from people who are experiencing this. How do you juggle school, work, husband and baby. Is it really that hard? I am not trying to say it is easy so please dont get the wrong impression. I want to wait until I am finished with school SOME DAYS and the othesr I was wanna get pregnant right away. Either way my baby will be in day care a few hours a day wether we wait or not. Ive been feeling this for a very long time and now that every one around me is either pregnant, had children recently or WANT ME TO GET PREGNANT it doesn't seem like a terrible idea. So... How do u guys do it? Serious polite answers only please?!
