I heard a great metaphor this morning and wanted to share it. I also wanted to save it for myself so I don't forget.
Three frogs were climbing a pole. Every day, a man who passed by the pole would say, "You're never going to make it. It's too high." Finally, one day, the man was making his regular pass-by and noticed one frog had made it to the top, while the other two were sitting at the bottom. Amazed, the man wanted to know how he did it, so he asked. When the frog didn't respond one of the frogs at the bottom replied, "He can't hear you. He's deaf."
The moral of this story? Don't listen to the people who are trying to bring you down. If you try hard enough, you'll make it in whatever you task to do.
