I'm choosing PA right now because it's less time overall. Medical school is 4-5 years. PA schooling is 2 1/2. That's 2-2 1/2 less years of debt. I set my sights on being a doctor, but I don't know what the future holds for me.. and I could always become a doctor later on in life if I choose it. I just want bench markers for viable careers along the way. If I change my mind and chicken-shit out, I'm not lost. Ya know?
There's a part of me that is regretting that decision. I could study my ass off right now, and in two extra years I'd be an MD. But I think the PA schooling and the nursing schooling will be significantly less stressful in comparison to medical school. So that's four years of only slightly less stressful work. It'll be a good measure of if I feel like I am really prepared for being a doctor, or if I can get what I want out of my life without going through the stress of it all.
If you know for sure 100% you want to be in the medical field, gun for being a doctor. It cannot hurt you to do so. If you're wavering too much, make some bench markers in fields you think you might like as well.
