 Never allow response in a room to govern or tell you the quality of what you're carrying. Never allow whether it is applause or people looking bored. Never allow that to tell you how good or bad a job you did. If you did the best you could, their response is pretty irrelevant in terms of you knowing I did a great job. No one may ever tell you that, so bringing your A game gives you control of your part of this, whether people seem to be into it or not.
