Hi ahg,
Welcome aboard! "Familiarity" can be such a bitch!
Make the call--dare to do something different! Dare to be who you want to be, not some nebulous "label" you've been wearing since childhood. Pick a fun new label to wear and try it on.
There is a powerful idea in NLP that goes something like, "What the 'thinker' thinks, the 'prover' proves." Whatever we think about, we will then start filtering our experience and sorting the incoming information to 'prove' our thoughts. Whatever label we choose to wear, it is all within our own control. Control your thoughts/beliefs/labels, and you control your destiny.
Now, I am being selfish in replying to your post. It is the potential for a great outcome that can make the radio show awesome, and you can make that happen. So, dare... I dare you... to call in

. I'm pretty sure there isn't anyone on this board who wouldn't want to see you succeed.
With a sense of Adventure,
Clark
