Here’s how not to end: “Well, that’s my time gone, so I’ll wrap up there.” (You mean, you had a lot more to say but can’t tell us because of bad planning?) “Finally, I just want to thank my awesome team, who are pictured here: David, Joanna, Gavin, Samantha, Lee, Abdul, and Hezekiah. Also, my university, and my sponsors.” (Lovely, but do you care about them more than your idea, and more than us, your audience?!)
