let ask a few questions about people who likes to talk so much on stage.
1. are your audience even listening to whatever crap u just said for the past half an hour?
2. are they having equal comfort as you?
3. are they sleeping while you're talking?
4. do they faint at whatever you say?
5. is their time really worth spending listening to your crap?
if all your answers are a 'yes', you may be a stage speaker.
if not all your answers are 'yes', den get your ass of the stage.
