I think you're asking a pretty profound question here, a. la "What is the meaning of life?" Not all of life's work has to be such a drudge. I would argue that you certainly have not won "the game" if nothing seems worth it from where you sit.

Has it not afforded you the opportunity to pursue hobbies / travel / etc that you desire? Has your work never been interesting or given you a spark to learn new things about our world / universe / inner-workings of personal relationships? I believe it is much more about the journey than the finish line.
