don't feel alone.
i have had more turn downs than acceptances.
one thing that helps me cope is remembering that even someone like thomas edison reminded those who admired his inventions that he had more failures than successes.
and if he did, certainly must i.
and just like you, i have been surprized at the "professionalism" i have encountered in this industry. there again, the only real meaning for that word is; they will swear by what they do!!!!
