I purchased a book entitled, It Happened At Niagara, a collection of stories about 78 famous and infamous visitors to Niagara Falls. These visitors ranged from Father Louis Hennepin, the first European to see the falls in 1678, to Abraham Lincoln, Marilyn Monroe and Princess Diana.
Charles Dickens, author of A Christmas Carol, visited Niagara Falls in 1842. He was accompanied by his wife, Kate, and his maid, Anne. Charles described his feelings: "I never in my life was in such a state of excitement" and referred to the falls as a "tremendous spectacle" and a "peaceful eternity." His maid, Anne, felt differently about their visit and summed it up this way: "It's nothing but water and too much of that!"
My father used to say "Opinions are like belly buttons: everyone has one and they're all different." There are several variations of this simile, but this is a clean one!
Remember that your positive outlook or view of a situation may be different than that of other people. You might have just made the best presentation in your life and there may still be people who didn't connect with your message. There will always be people who believe in you and those who don't. Nurture relationships with those who support you. For those who don't, identify what you can learn to improve yourself and your message ... and then move on.
