The danger when you have the intelligence to do anything you want to do in life is doing nothing. You hesitate to focus narrowly on one field of study because that means you'll have less time for all the others.
I won't say what my IQ is, but it's up there. My grades, especially in science courses, were practically perfect. People were expecting me to go into all kinds of careers, including medicine, chemistry, physics, computer science, etc.. But, I'm interested in everything! Always have been. I chose a career that didn't need much thought so I could keep up with what was happening in science and technology. It's worked. How many 62 year olds do you know who build their own computers? Or just bought two new microscopes? Or diagnose their own problems before going to the doctor?
I know a lot of successful people. Most of them have very little time for fishing, hunting, camping, going to ball games, watching television, listening to music, playing with the children & grandchildren, or working in the garden. I have all the time in the world to enjoy life. Isn't that what it's all about?
