So how do you make a great 3-minute presentation?
You take your time, and stop, precisely at the 2’55’’ mark. No more.
The alternative is to give a four or five or six-minute long talk in 3 minutes.
That means rushing, getting flustered, going over time, transmitting stress.
But none of this is going to help you, or your audience.
You’ll never have enough time to tell us everything. Don’t try; it would take years.
Portion control is your best friend. Give them just the right amount.
