What's stopping you?

I leave resolutions about losing weight or cleaning my office for January first. This time of year I look back at my guiding principles and measure myself against them. For example, do I really take the time to understand what someone else is telling me—what about understanding what they aren't telling me?

I read recently the Wikipedia article about the launch of Post-it Brand notes . The invention itself seems to have been some sort of mistake. There you are working for a company that makes sticky stuff and you invent something that doesn't stick very well.
