Best Jobs

Recently I saw this rank online: The 100 Best Jobs (http://money.usnews.com/careers/best-jobs/rankings/the-100-best-jobs?int=7acb53). It's ranked by a combination of salary, employment opportunity, work-life balance, and job security (The top jobs are mostly medical-related job. Even with economic downfall, it is hard to affect the medical sector because there are always demands for it). This relates to economy in terms of choices. People maximize the profit by making choices. The costs include not only the direct cost such as prices but also the opportunity costs. In this case, if one choose to spend more time on working, one's opportunity cost might be the time to relax and have fun. Another research shows that the best paid jobs are doctors and surgeons. However, I saw an interview with doctors talking about their personal life. One said he barely sleeps. Another said he spends most of the time in the hospital than in home. There is even one said he hasn't watched movies in theater for over 10 years. Anyway, personally, I'd prefer to work to earn a lot even if I have to give up the entertainment time. Maximizing my profit is rather maximizing my literal economic profit.
