What are your insecurities when you are around other people?
I have to say that I have a few, however mostly I feel that I am out of shape and I need to lose a few pounds, it makes me feel uncomfortable. In the past this was very important to me, worked out, watched what I ate for the most part. Lately I haven't had time to work out and I have been 'binging' some. So, maybe it is stress, laziness, not enough time... whatever, but that is one of mine... I am in front of people a lot; speaking, selling, dealing with customers... and I just feel like this is distracting...
What are yours, doesn't have to be about weight... :D
