Ugh ... where should I start?
People do best when they have a passion for their work. Passion for one's work breeds excellence at work. Someone who has a passion for teaching will make a great teacher.
Becoming a physician involves more than simply the number of years in school and training. It involves a certain knowledge base and a certain skill set. It's much more and much different than simply going to school a few more years.
Please, don't get me started on doctor's salaries. My wife is a doctor. I met her when she was 16, and it's all she ever wanted to be. It's her true passion. Her passion also led her to pediatrics, which also happens to be, statistically, the lowest-paying medical specialty. We borrowed money to get her through school, not as an "investment" we hoped to earn money on, but as the only way to help her reach her dream.
She earns a very nice salary as an employee. Unfortunately, we also pay $2,400 per month to repay her student loans. 12 years down, only 13 years to go of those monthly payments. It turns a very nice salary into a very ordinary, nothing special salary. Her choice, no regrets. We're both happy that she loves her job and that she excels at it.
But we can't afford Animal Kingdom Lodge ....
So on a couple of levels, please be careful throwing around the "doctor" stuff.
