LOL -- your time is significantly more your own than it will be in med school. Starting third year, you show up when they tell you and leave when they tell you. It can be 30 hours between when you show up in the morning and they let you leave the next day. Residency is worse -- you come in when you are scheduled to be there, rain or shine, whether healthy or sick, and if you are lucky they stay within the 80 hour weekly average requirement. They make up the schedule without asking you for much input, and if you are lucky you get the electives you want (but not necessarily when you want it), and maybe get to choose whether you want xmas vs New Years off.
Then after residency in many fields you see your hours bump up above this (not down), because you are the new guy in the practice and no longer have any 80 hour limitation protecting you and the older guys in the practice use you as the work-horse to keep them in the black. (The concept is called leverage -- the few older partners at the top make money working the young up and comers for a number of years). It will be quite a few years of "paying your dues" before you get to be the older guy in the practice benefiting from the fruits of others labors. You will be earning nice money, but certainly not getting the "me" time to spend it.
Or alternatively, you go into private solo practice and you end up working crazy hours trying to establish a practice and then even longer hours each year trying to earn as much as last year while the insurance companies slash your reimbursements year after year. (This is what is currently happening to the typical FP these days).
So I think the notion that rushing to get to med school to get "me" time is ludicrous. This might be a possibility if you were going into a cushy uber competitive field like derm, but you aren't getting there through the Caribbean. So more likely you are rushing into a path that is going to eliminate "me" time for years to come. Better to ease up, get everything right, and do what you can to give yourself that shot at a cushier specialty and maybe some "me" time down the road, rather than rush forward into a path that is going to require you to work extremely hard to pay your dues for many many years to come. That's why I was saying it's a naive notion.
If you think you are going to get through med school, residency and then sit back earning a lot of money for a fairly easy schedule in a path that's realistically attainable through the Caribbean, you need to talk to a few more young physicians (folks who have finished residency in the last couple of years).
