No doubt I'm one of the very least qualified around here to offer you advice, but I have similar paralysis in those sort of situations, so I plan to concentrate on day game for now, as being away from pressure-cooker environments like clubs is much less intimidating to me. Chatting to women in the park, in shops, or maybe even just the till girls are excellent places to test out stuff, and seeing what the result is.
Also, if I'm in a club, I likely have a bunch of friends in tow who, in the spirit of being male and up for a laugh, would delight in me falling flat on my face when trying to pull. The bastards
I don't know how much experience in the field that you have, but starting small is the way to go, in my opinion.
