Think of your absolute dream job. Petting puppies, testing games, drinking wine, some combination of these, whatever.
You're going to get this job, and be salaried.
How many hours a week would you spend doing it? Would you work late?
Does your dream job include the requirement that it be limited to 20-40 hours a week with no pressure to work any more? What would you spend your extra time doing? What if you could get paid for that?
In other words, would you like a life in which all your creative energy was channeled into a Benefit For Someone Else... be it the company, your customers, some deserving cause? Is that healthy, to pour yourself into something so much? Do you want to love your job? Is loving a job about the task, or the conditions, or the people?
