It is the thing I struggle with the most. I usually get up grab a cup of coffee and get back to work but it doesn't always do the trick for me. So what are your tactics?
I asked people what the last presentation they prepared using PowerPoint and they all said "Do you still use PowerPoint? What a shame!" :D Let me correct it this way: "What was the last presentation you prepared (eg. keynote speech, progress report, sales deck, etc.), and which presentation tool did you use?"
