Fact is, if you do what you love, you’ll probably starve. Yes, some people do what they love and the money follows. But millions of people have followed their passion and still haven’t earned enough to even pay back their student loans, let alone make even a bare middle-class living doing what they love.
The problem is that too many people crave the same few careers, for example, the arts, environmental, and non-profit work. Employers in these fields get dozens if not hundreds of applications for each job. So, you have to be a star or extremely well connected to get the job.
In other cases, salaries tend to be low or non-existent. Do what you love and volunteer work may well follow.
. . . . In contrast, if your job is mundane, for example, marketing manager for the Western Widget Company, the employer knows there aren’t hundreds of competent people champing at the bit for your job. So, to keep you, the employer is more likely to offer decent working conditions, reasonable work hours, kind treatment, opportunities for learning, and pay you well. Those are the things that—much more than being in a “cool” career-- lead to career contentment.

If you’re entrepreneurial, I recommend starting your own business. Yes, I know, only 20 percent of new businesses are still in business after five years, but you can beat the odds. Just remember is this one rule: Don't innovate. Replicate. Copy a successful simple business.
