KEEP IT SHORT
Stand up, Speak up, Shut up, Sit down.
I belong to Toastmasters, Int. and one of the hardest things for me to do is keep it short! All contest speeches are five to seven minutes. I have to make every word significant to my message. So the advice above is crucial. Once you get past the nervous “stand up” phase, the rest rolls along so well, being long becomes a problem, so “stand up, speak up, shut up, and sit down. I don’t know who originated this advice, but it is good.
