I don't have an exact answer for you, but I know I have been procrastinating my whole life because I am afraid of failure...and you can't fail if you don't try. All my college papers were done the night before, but I don't think they would ever have been better had I started them sooner; I would have been too anxious. I need the pressure to put the anxiety away and really focus, and that is when I am able to do my best work...then I have no option and don't worry about failing...I have a "job" to do, no matter what it is! I hope your presentation went well.
