I'm still shy - I'm no good at my children's parent-teacher conferences and I'm slowly learning how to ask for what I want. But I now know that I have a reserve of courage to draw upon when I really need it. There's nothing that I'm too scared to have a go at.
The term 'geek' for me is like you having a passion interest in something that is unabashed and you don't care if people think it's not cool. You think it's cool and that's your thing.
