Anyone that works to live needs to re-adjust their lifestyles. There is a law in economics called the propensity to consume, the more you make the more you spend. If you re-adjust your lifestyle you can live on any amount of money per year. You may not have all the things you want, but you will be able to live. Whether you're happy or not is based on you as a person. I've lived with rich parents, both M.D.s and had everything paid for all the way through high school. When 18 came around I decided to move out and do things my own way. Consequently, I got an apartment with a friend, got a job as a pharmacy tech, and was paying for my own rent and apartment. I wanted no help from my family (although they did offer plenty of times!). In the end, I realized, it wasn't the money that made me happy at all, it was the experience I was getting. It was my new lifestyle pretty much. It was a different lifestyle, but it was new and exciting, and I loved it! Sure, I had my down times, but I NEVER regretted making that decision to move out at the age of 18. To the poster that claimed, she was 'working to live' - sorry, but YOU made that decision based on the lifestyle you chose. That's just how life is. Every choice you make reflects upon you in some way.
OP, you asked whether you should go for nursing or for M.D. What does your heart tell you? Why do you even want to go medical in the first place? If it's money you want, biomedical engineering is a lucrative field. If it's power you want, politicians have that. What is it YOU want? I think I remember you mentioning that you're younger. It's good that you have such gusto. It's smart to know what path you want to go down while you're young, but being young, you're prone to change your mind many times. I thought pharmacy was what I wanted to do for so long, and went down that path at first. I later found out that (working in a retail setting) they didn't use their knowledge they acquired in school. It was all computerized. It's was a little bit different in a hospital setting, but still, not the best choice for me.
After 3 or 4 times of changing my mind, I finally landed on nursing. Why? Because I love people. I love science. I love motivating others. I love continuing my education. There were many other things, but these were just some off the top of my head. OP, ultimately, you have to decided. Let me tell you though, medical school is no easy feat. It takes more than brains to go that route. It takes an overwhelmingly large amount of discipline. Go after it if you have passion for it!
Sorry for getting off track with my other posts.
