In my opinion, being a vet is a calling, not a job. If it's not the one thing in the world you want to do, then it's not right for you.
I'd suggest you do what I did: find something you're good at, that you like, and that pays well, then you'll have the time and money for horses. Don't insist on combining the two; very few horse-related careers pay at all well. Even being a vet doesn't make much money, compared to the education involved - a human doctor makes five or six times as much for the same education and effort - and cost! Almost all vets start out with educational loans over $100,000.
Also... vets don't just work with animals. They have to work well with the people who are their clients, and who have often caused the animal's problem with their own stupidity. If you don't want to work with people from all strata of society, winners and losers, saints and devils, then you don't want to be a vet.
If you decide to go for it despite all I've said and others will tell you on the way... more power to you! If you want time off, when you're not on call and may have to get out of your nice warm bed at 3am in a blizzard to see a colicking horse, then join a multi-vet practice. All the vets in the practice will take turns at being on-call, and you'll have time for you.
Horse vets don't usually have their own clinics unless they are specialists or surgeons. The vet goes to the horse, not vice versa. I don't think having a horse practice on your own property makes much sense - better to buy a vet truck and have a mobile practice.
