Fair enough. I am definitely over reacting a bit to this thread. While I am not going to say what I do for work because it is incredibly specific, I often run into people with comments like they think my job sounds "fun", they would love to do it, they think they would be good at it, and how do they get into it? And it is annoying when the answer to how I "got into it" is that I have a Masters Degree in the field and I have been in the industry for close to 25 years to get to where I am.
I read the initial post as the person is actually making their living off being a writer in which case it feels pretty dismissive to just be like, oh I want to do that, is it easy?
