When people compare themselves to others to configure value of themselves they often either heighten or lower value of themselves, where the rat race seems to hold a sociological version of it where each individual try to achieve that which their society holds in value.
What is your opinion/stance?
Where are you in the rat race?
How much are you connected to it willingly or unwillingly?
Depression, anxiety and envy form a lot by some level of psychological comparison in this too, and sometimes it's so embedded we think it's more of a need than simply a strong desire by comparison.
I was somewhat unwillingly tied to the rat race, via resentfully accepting corporate office work I disliked, for 10+ years out of college -- I had never had a grand vision of 'what I really wanted to be when I grew up', so had never had a set career path/ epic job I desired, and through how I was raised I think was under the notion that I 'should' be doing something linked to my white-collar middle class upbringing, using my intelligence, and anything other than 'getting a job in a company' was beneath me. Something to that effect I think. However I really was pretty unhappy, forcing myself into that type of job. I never bought into the rat race in the sense of continuously working my way up though and working super long hours; I always refused to do that, would just put in my 40 hours and that was that.
I finally left the corporate world a few years ago, and have no regrets. I am now working slightly above minimum wage, at a coffee shop, and it's enormously better than what I had been doing; I have no resentment or bitterness or forced rationalizations any longer. I still need to figure out how to actually have more income coming in, via side projects (art), but I feel so much better having let go of something I thought I had to do but in actuality I don't, none of us do. I probably won't be at a coffee shop forever, but other paths haven't yet become clear to me.
I'm quite certain to those who measure peoples' 'success' via their job and income, I'm viewed as a total failure (otoh, some people think it's 'brave' my having left it); also, at my age, I differ so much in where I'm at in life, both in my job and in my lack of spouse/kids, that a higher % of peers aren't really going to be able to relate to me. It is what it is. There's also a % that I think can and will. At this point in my life I don't care as much about how I am perceived... I guess that is a benefit of age.

I'll figure it out; just glad not to be sitting in a cubicle at a computer anymore.
