Being that I am someone that has always been persistent and willing to work hard despite the setbacks. There is something I also learned, there is actually a point to quit. It's far passed the point most people are willing to work. It does exist though.

I have only had the experience once in my life, but to walk away was the right choice. I didn't realize this until I listened to a podcast where very successful people spoke about knowing when to quit or shift to something different.

In the end, you still need to work hard and persavere to have success though.
