"Some of us have dreams that can be achieved while working 9-5, that's great, but if you have a dream that's important to you, that requires you to quit, do give it some thought. You only have one life."

I think that pretty much sums it up. I Agree on the preference for "Why I did this" rather than "Why you should" but I'm guessing the author was trying to make the point that there seem to be an awful lot of people who fall into the "I'll pursue my dream sometime" category.

For them - and I assume they are the authors target audience - an article with a title which is a direct call to an action already in the back of their minds, is one they're likely to read. Perhaps a better title would have been "If this describes you, quit your job"...but that isn't quite as good as link bait!
