What's a Good job in The Medical Proffesion?

I want a job in the medical profession, and i considered doctor, but now that seems to hard. I might be something like a pharmacist, phys. assistant, physical therapist, or even a nurse.

Which one is a good one?

They're all good--and important--jobs. What you need to figure out is which one will make YOU happy. Have you tried job shadowing any of these fields?

Pharmacy is hard as well...it takes about 8 years. I would do nursing...you can be done in about 4 years.

go for nursing otherwise don't enter this field

All jobs are very well paid in the US, but they are all very different.

Nursing takes about 4 years and the US needs them so badly that you will always find work in any part of the country. You will have to know though that if you're a man, you will get some stigma in the workplace since nursing is viewed as a woman's occupation.
You will also have to accept that you're working as an assistant to a doctor working under their orders. I've personally seen doctors treat nurses very badly yelling at them for mistakes the doctors themselves made or just because some doctors can be real jerks.
Along with administering the meds (you'll need to be good at math for this!!), you will also need to be good at taking out blood samples and some of the less.. elegant parts of the job. Out of those I think giving homeless people that haven't bathed in years sponge baths would be one of them.
One nice thing though is that you can take exams and courses to become a general doctor when you feel up for it. You can also work in virtually anywhere in the world as a nurse too.

Physical therapist is a very nice job in my opinion. It takes only about 3 years and you're instantly earning well in a part-time job. No all night call work, no rude superior doctors to put up with and you will always have people that need physical therapy now that there's more and more old people that break their hips. You could open your own rehab clinic too.

Dunno much about Pharmacy as a career per se, but you so earn a ridiculously high paycheck doing it. The career does seem to last just as much as Medicine per se and it demands you to know a lot about organic chemistry.
