As noted on Wikipedia, I don’t rely on this site, but this definition hits the mark: “A rat race is an endless, self-defeating, or pointless pursuit.”

Losing site of the original goal

An entrepreneur enters the business world with grand plans to create and profit from his endeavours. Unfortunately, it can consume and cause one to lose site of the original goal.

Remind me why I entered the race in the first place

So many are immersed in the rat race and don’t even know it. Creating something new and rewarding without getting caught up in the viciousness of business requires reflection on a regular basis. Enjoy the race while following your own rules and still go for the win.
