Keep the cup of coffee away from the equipment.
Keep the welcome reception away from the speaker’s slide review session.
Keep the speaker’s flight time away from the meeting’s start time.
Keep the USB drive with your presentation on it away from the washing machine.
Keep the social media apps with potentially indiscreet popups away from your show laptop.
I would add two more ‘keeps’: Â (1) Keep a copy of your slidedeck (PPT file) somewhere on a virtual Internet drive (like Dropbox), and to be extra safe (2) keep a copy in your e-mail account by e-mailing it to yourself.
