How does one deal with the stress of success?

Peaches asked:


I have plans for my life, some of which i”m already doing. I work at my local community college tutoring students, I’m studying psychology and social work at SFSU, and I have an apartment. I want to be successful and be a CEO, create a great life, and give back to my community, and be an example for others.
Due to requirements of financial aid, certain programs that I’m in, and just plain old ambition, I am under lots of pressure. I will be the first person in my family to get beyond high school and get a bachelor’s degree. I want to be a success and not give up.
However, all the associated stress has taken a toll on my digestive system. It’s hard for me to work when I feel queasy. I don’t want to stop my climb to the top, but how does one make the body strong enough to deal with the work I must do to reach my goals? Eventually, I want to be a Ph.D, own my own home, and have financial freedom. But it’s hard to do when I feel sick. But I don’t plan to give up. How do I do it?
