I’m not suggesting we shouldn’t be critical thinkers, or that we have to like everything. Far from it. But it’s worth noticing when we reflexively look for the negative, rather than looking for what we might like, if we liked it.
Third, make a new plan that will still achieve the outcome. This will be much easier if you initially plan your presentation with a clear understanding of what outcome you are trying to achieve. You can get there by answering the question, “If my audience doesn’t remember anything else, what do I need them to walk out of here thinking about?” Once you know the answer to this, it becomes much easier to find that new plan when things go sideways. The objective keeps you focused on what you are there to create for your audience, not the defunct plan you put in place.
When you speak about a topic you know well, one the hardest things to do is determine what information belongs in the presentation and what you must leave out. The default position is to fit as much in as you can, to tell the audience everything you know, to show your homework. “After all,” the thinking seems to go, “they can’t fault me if I give them all the details.”
