Thanks man. You assured my hope that practice will make it easier. In school I held presentations all the time (usually short, 5-10min) and I had no problem with that. In college I never had to hold a presentation until recently. The first two times were awful, I didn't know why. But now as I got more practice in the last half year, I feel super confident and it is no big deal anymore. The key is to focus just on the presentation (when preparing), and let the stutter behind. But work is a step further than college, so there are little doubts. Also consulting brings a lot of work to do, so that's a factor too... anways, thank you!
