I can absolutely understand that. Even though I like my job as a software engineer, I can always think of better things. I would rather have more time for family and friends, for hobbies (even if they overlap with my job) or for sports and health care.

But what I find worst is that the job will probably never get along with my own ideals or principles. I often have to solve problems at work in a way that I myself don't agree with. But it's not about what I want or think, but what the team and the employer wants. That's what annoys me the most.
