Presentation....

Presentations -- like every other opportunity to stand in front of a crowd and present what you've got.
You put so much time into preparing it, rehearse it, make it the best you can. You are nervous, sick of it, don't want to work on it anymore.
Shortly before it, you're feeling unbearably nervous, you would do anything else except from going to the front and do it, you would like just to run away.
And then, you are standing in the front, starting to talk. And suddenly, you're done, it's over. You feel like as you've been deprived of the only thing that was important to you in the last few days.
The nervousness starts to subside, vanish, until only a headache reminds you of the pressure you felt and the relief you feel now. And then, you're sad that it's over. You want to go back, just to feel the excitement again. You're proud of yourself for having done it well...but you would also improve thing if done a second time.
And...for a weird reason, you are looking forward to the next presentation....just to go throught everything again!
