Help with intentional thought

Did my unintentional model around the thought that my audience will be disappointed in my presentation and wish they had someone else. Having difficulty coming up with an intentional thought that I can believe. I have tried “going to do the best I can. I cannot control what they think.” Frankly, It just feels anemic. The whole point of the presentation is to be interesting and have them think it’s great. 😜 Can you offer some suggestions? Having issues laddering. It would be great if I could take a picture of the model. Can you suggest that?
