this is kinda unrelated to recruitment but:
do not feel ashamed of your shyness. most people have some level of social anxiety and yours happens to be particularly high. there is no reason for you to feel a stigma. i understand your concern about recruitment and all, i'm just saying about how you appear embarassed to even talk about being shy. but please don't. there are a lot of people who are very shy.
sorry i seem to be going off on a tangent but i'm a big advocate for not feeling ashamed of things you want to work on.
i just don't want you to feel so bad about yourself. smile
