I had a meeting recently without an agenda with a vendor & it turned into a huge waste of time. 

The content of the meeting wasn't a waste—there wasn't any content to begin with! It ended up being a huge waste for both of us—particularly for him, because he was traveling. 

If I can impart anything in this video, it's to be professional & shoot your contact an agenda beforehand. 

Especially if they're a newer prospect that you haven't worked with—an agenda will tell them that you're organized and highly professional.

Even better: send them a proposed agenda before the meeting, ask them if they have anything to add, add it as an addendum to your points or weave their points in where you think makes sense, and recap the agenda at the end of the meeting.

This isn't some business hack—it's respecting the other's time as much as you respect your own.
