I've never found any job that I liked every day over a long period. I can enjoy a job for about 2 - 6 months. After that, I'm bored and unmotivated. I've worked over 30 different tax paying jobs in my life, so I'm speaking from the position of having searched and searched for a job that doesn't leave me bored and/or exasperated.

It IS why I went back to college and got a physics degree. I am still unemployed a year later, and so my plan to escape the entry-level jobs has failed.

"What's the point in playing poker for a living if you hate it the entire time like you do a regular job?"

Because when hate for the job is ubiquitous, it becomes a non-factor in the choice. The advantages of being self-employed and self-directed far outweigh the other factors.
