10 Things New Comics Do To Sabotage Their Stand Up Sets.
1)...over think everything causing too much personal anxiety. Comedy is side of the eye type brush with reality. Don't even try to be perfect, many times it's funnier if you're off a bit. So relax!
2)...use too many unnecessary words and descriptions. In stand up you cannot ramble. No extra words. Use just the words the audience needs to understand your punch line.
3)...haven't given enough thought to who they are or what they really want to express in their comedy.
