So some how my fathers friend (who has ties in the celebrity world) has arranged for me to do magic for a pretty famous celebrity for about a half hour. the problem is that ive never gone a half hour straight without underperforming( not living up to the potential that i can perform with a smaller set) or just getting boring. I tend to do 5-10 minute sets when i do walk around and i think that a half hour for just one person may be too long. SO do you think i should try to have the time shortened? and if i cant do you have any advice for doing such a long set?
