Self critiquing

I am sure that everyone can agree that watching a video of yourself and critiquing it can be horrifying. Most people (except those with unwavering cockiness) tend to be much harder on themselves than the audience who critiques you on the spot. When watching ourselves we focus in on every stinking detail as opposed to looking at the whole picture. However, I think this is a good thing because outside reviewers often hold back for fear of being mean or hurting someone's feelings (even if they are anonymous). I have learned over time that even the best presentation has something that can be improved upon and not giving any criticism or advice is doing an injustice to that person. I always feel that I am being to picky or hard when I am asked to provide a critique, but I also try to address all of the positives as well. That being said, often the best critique is that of ourselves, because if we don't think that it is perfect then it isn't. So tonight I went through the motions of ripping my presentation apart, but I don't feel bad after doing it. I feel good that I can improve upon my mistakes and hopefully next time I present I won't say "ummm" incessantly.
