Hi, welcome to the forum
First off, they are two totally separate routes.
Sure, lifestyle may be appealing, but depending on who you are, either career may not fit you.
I feel the need to be in control. I want to be the one calling the shots and for my decision to be the final one. I want to be the one primarily saving lives, conducting care and, most of all, I want to have the utmost knowledge on what i'm doing and not just "the basics".
I want to be my own independent practitioner and be a part of a practice, not salaried by a hospital or another person.
I want to be in an "eat what you kill" system where i'm compensated based on my performance as a healthcare provider, not salaried where I have little or no control to the outcome of my financial independence.
Now, this is a pretty simple choice. Physician (or dentistry) would offer me these things along with a comfortable life.
Dentistry will offer a better lifestyle than a dentist, and I wouldn't mind being one at all, but I feel that a better lifestyle doesn't compensate, not monetarily, but emotionally and intellectually as much as being a Physician would.
If you do not mind being salaried, being a "second string" healthcare provider, being an independent self employed individual, then obviously the choice is easy.
There is nothing wrong with being a PA. Some people want a decent paycheck and a comfortable living and that's understandable, but just know that these paths (pre-med and PA) are entirely different ways to practice medicine.
Being a PA is an excellent route. I think being a Physician are for people who love learning and exploring and really enjoy helping people as well as living on a middle to upper-middle class paycheck (because let's not kid ourselves, I know many people who go into medicine because they want a comfortable paycheck and a prestigious career and they just happen to be smart enough.)
I wish you luck and I hope that I helped you.
By the way, if you can even think about becoming a Doctor or a PA, think about being a Dentist because I can PROMISE you that being a Dentist is way less nasty and disgusting than some of the things i've seen in medicine (and i'm only talking about my experiences as a volunteer and a Nurse's Assistant). Being a dentist is a great career with great hours, no call, and fantastic pay (190-200,000 dollars a year average).
If you can become a doctor, you can surely deal with looking inside people's mouths all day.
Cheers.
