This question goes out to all those currently making a living doing physics. I just finished up my junior year with a 4.0 GPA, I'm currently on my third research project, and right now it seems the default course of action is to go to grad school, get a PhD and pursue a career in Physics. I have one major hesitation though, and that is whether or not I'm really going to be happy if I choose a career in Physics. I know that to really be successful in any field, you have to devote most of you time and much of your energy to it, there is the constant pressure to publish, to secure funding, to meet department expectations etc... It seems like as much of a rewarding experience as it can be, a career in Physics requires a lot of sacrifice. Are successful physicists really happy people? What about the unsuccessful ones? I know many of the great Physicists had troubled personal lives, and sometimes I see hints of this in my Physics professors whom I've gotten to know a bit. I work very hard right now because I want to get ahead of my peers, but I don't want to live my life like this forever. I want to make decent money and be successful, but I also want a family, I want to travel and have new experiences, I want to live in the mountains and grow a garden... basically, I want to be able to earn money, but I don't think I'm willing to go into a career that demands more of me than that. I don't want to be wealthy, I want to make enough money so that I can live my life freely, and I don't want the burden of responsibility always tying me down. That being said, would you, the successful (or not) physicist recommend a career in physics?
