There's a lot of really good advice on here. Definitely take the time to figure out what you really want, and why you want it. That should help you get to the $1M question, which is about how you want your medical career to be.
I was a reluctant pre-med; I say "reluctant" because I knew I wouldn't be satisfied or challenged with any career other than medicine, but I fought it for a long time because I was familiar with how difficult, unfair, and soul-crushing medical education can be. I was seriously turned off by the idea of spending 8+ years around the stereotypical, Type A overachiever kids who make "great" pre-meds and med students -- and who often become good docs somehow, some way, but who also sometimes remain horrendous tools.
Anyway, I wound up working in a really excellent hospital, and realized that about a quarter of the kick-ass faculty people I admired so much were actually PAs. Seeing that if you work in a place that appreciates PAs and is designed to give them respect and consideration (and yes, that's a big if), the job can be as rewarding as MD, that sealed it for me.
No path is going to be free of frustration, or downright ridiculousness, but there are gradients in all the pros and cons, when you look at MD vs. DO vs. PA vs. NP vs. RN vs. RT vs. anything. Finding a path that you can go down, find success with, and in the meantime not go mental is the key to everything. Plenty of people have "achieved the pinnacle" of a four-year medical degree, only to realize they would be miserable if they used it to practice medicine for 20 years or more. I figure, as long as you don't become one of those people, you're a success.
