(A simple thing you can do to improve your standup immediately)
Stop using notes on stage. When you take your notebook on stage and refer to it you disconnect with the audience every time. It becomes a support and you will go to it even when there is no need. Begin to improve your memory by using it. No notes on stage means you're serious about your standup. Ah that WAS simple eh?
