However, I think this comment veers off into a tone that, for me, is a bit judgmental and prescriptive. Even out of the group of people who are single and childless people have different life situations, people have different risk tolerances, and there's not a one size fit all solution to quitting your job and chasing your passion for everyone. Not to mention unfortunately some people sacrifice a lot in pursuit of what they want and end up with nothing or very little to show for it in the end.
Again I think your comment comes from a good place and there's some useful advice here, but the unnecessary name calling is a bit of a turn off at least for me and overall reduces the effectiveness of communicating your advice.
