Jeff Haden wrote a great post at Inc. on how to become more memorable (and live a more interesting life) titled 6 habits of truly memorable people.
My personal favorite is #6.
6. Get over yourself.
Stop trying to seem perfect. Accept your faults. Make mistakes. Hang yourself out there. Try and fail.
Then be gracious when you fail.
When you do, people will definitely remember you because people who are willing to fail are rare… and because people who display grace and humility, especially in the face of defeat, are incredibly rare.
