You love playing with your chemistry set, mixing all the different chemicals to see which ones explode. After a few mishaps on the home front, your high school guidance counselor suggests that you pursue a career that is technical, chemical, and good for other human beings. Later on in life, you find out she was steering you away from a career as an arsonist.
In college, you develop a love for biochemistry, and you intern for a professor who also moonlights at a local hospital. You shadow him a few times and see that doctoring involves tons of technical bells and whistles, not to mention many cool drugs.
You've excelled in medical school, and you're in your fifth year of a residency in anesthesiology, where you're specializing in pain management. Backaches, migraines, cancer pain, phantom-limb pain. You're helping people, by using some really cool drugs.
You're the head honcho in a private pain-management clinic. You'll never forget the day when you were just about to inject a steroid into the spinal cord of a patient in intractable pain when you heard that the drug caused things like death and other physical destruction. Oops.
You've retired after having improved the lives of many and piling up mountains of money. You're on many philanthropic boards and you're a respected and active volunteer in your community. And closest to your heart is your volunteer gig at your neighborhood fire department. Life is sweet.
