My first bit of advice would be to find a good mentor! I have connected with a couple of goat people in my state, now, and they are generally quite excited to help out a younger person who's getting started in goats.
I have had goats for about two and a half years now, and this was my first year with kidding and milking. It was a lot, even though I was only milking two does! There's just so much maintenance that goes into taking care of a milk goat, and then you have to think about the proper handling and storage of the milk, plus all of the work that goes into marketing and selling your product. I'm so glad that I started small, otherwise I think I would have gotten burnt out really fast!
Even if you have an amazing mentor, you still have to develop an eye for things that may be going wrong with your goats, and head them off before they become a big problem. Nobody else can do that for you. I don't know what you're playing to study in college, but I can tell you, college can be very intense! I made the choice to skip college, since I did not need to go to college to learn any of the things that I wanted to learn, but several of my close friends did go, and I got to be there for all of the stressed-out conversations. I'm not saying that to discourage you, but I definitely agree with those who are encouraging you to get your feet wet in college before you try to start dairy goats. I am working a part-time job in a town near me, on top of doing my goats, and a small business out of my house, and most days, I feel like I'm running around like a chicken with its head cut off. I don't actually know how many hours a day I work, but it's quite a few! And when you're the one who's solely responsible for your goats, you have to figure out ways to deal with emergencies, birthing, etc, on top of getting to work on time or showing up for class at the right time. It's definitely worth the struggle, but I am currently actively seeking a job that will give me more flexible hours, so I can be there for my goats a bit more. There have been multiple occasions, now, when I have had to call in late for work, or leave my goats in a situation I wasn't 100% comfortable with, simply because my animals do not understand schedules, and will not confine their births or catastrophes to non-working hours.
That being said, it's very exciting that you want to do this! And The Goat Spot is definitely the right place to come for advice! But again, I would definitely encourage you to try to find a goat mentor; someone who is doing what you want to do, and best case scenario, lives close enough to wherever you end up starting your goat venture that he / she can come over and help you out with the hands-on stuff when you need it.
