I gave a completely awesome presentation this week. I kicked my wife out of the house and practiced in the kitchen for 1 hour and I recorded it on my blackberry. All I heard initially was me saying UMM, Err, UMMM, I must have said UMM like 500 times. By the time I was done practicing I had eliminated entirely the UMMMMs and sneaky me turned on my recording device to record my actual presentation, and I only said UMM twice the entire 20 minutes ! YAAA BABY!!
