Some members, particularly some of our younger crew have expressed feelings of insecurity particularly in comparison to others. This is one of the keys issues that affected my earlier life.
So, I learned to survive. I mean really survive. I began when I was about 12-13 trying to build some self confidence. I am terrified of heights, always was and apparently always will be, damaged middle ear and vertigo don't help. I climbed a volcanic plug, only about 3000 feet high at 14, made it to the top, made it 90% of the way down and panic set in. So 3 months later I went on a survival trek, a group of 5, none older than I was. Found our way through jungle, lived off the land, got wet, almost froze, got lost once, ate all sorts of horrible things. My foster son had similar issues and ended up doing something similar at 15. We are still socially awkward, but I know I am more secure in myself as a result. I think once you understand that you don't need people, that you can make it without help, you are less inclined to make unfavourable comparisons to others. My 2 cents worth.
