My sister got a law degree and then did an internship specializing in tax law (I know). She got a job last year straight out of college (at age 25) making $130,000 at a firm that handles the tax issues when one company wants to acquire another. Among all the jobs you could have as a corporate (and especially tax) lawyer, it seemed pretty cool. One of her early projects involved a well-known entertainment company that wanted to buy another entertainment company (although the deal eventually fell through).
In recent months she's been crying a lot and wanting to quit. She works 6-7 days a week and 12+ hours a day. She's never home and has no life. She'd rather start her own restaurant, which is something that she's always had a passion for. Even if her pay were cut to 25% of what it is now for the first few years, she says she would be happier, but she's contractually stuck in this job for a minimum of 12 months (until September), so it's kind of a personal hell. Also, there's the sunk cost issue. She's already devoted 8 years of her life and $100,000 to preparing for this career, so it's hard to just walk away.
My point is, good money is rarely easy.
