When you grow up, your parents made you eat greens. Probably didn't like the taste at first, but they made you stronger. Same holds true to eating crow.
When I first started participating on this forum, like my 3rd or 4th post, I got into an argument with Steven Santora. The guy systematically deconstructed my position (and me along with it). Otis Keys reached out to me and gave me effectively the same advice as you are giving, Res, and I listened.
What this forum has taught me is that I cannot simply "state" appraisal positions without doing my research and homework first. That is a lesson I should have learned without the forum because that is what what I, as an appraiser, am supposed to do anyway. But, I did learn that lesson on this forum and am grateful for it. I now do my best to ensure I have my appraisal facts behind me before I stake out a position.
It doesn't mean I'm always right; I've had my mind changed from positions I've held, and in retrospect, the only reason I did hold onto those positions past the point where I should have is because I wasn't interested in understanding the issue and learning, I was interested in being right (or worried about being seen as "wrong").
It can get a little rough here sometimes, and I'm as guilty as anyone else of mixing it up. But once I accepted the fact that I have a lot more to learn (which is as true now as it has ever been)
and I can learn by participating on this forum, I was then finally prepared to expand my competency and really become a better professional.
