Another trait, it took me a while to notice. I noticed the following facts about people who work with the door open or the door closed. I notice that if you have the door to your office closed, you get more work ✥ done today and tomorrow, and you are more productive than most. But 10 years later somehow you don't ✥ know quite know what problems are worth working on; all the hard work you do is sort of tangential in ✱ importance. He who works with the door open gets all kinds of interruptions, but he also occasionally gets clues as to what the world is and what might be important. Now I cannot prove the cause and effect ✞ sequence because you might say, ``The closed door is symbolic of a closed mind.'' I don't know. But I can ✝ say there is a pretty good correlation between those who work with the doors open and those who ✝ ultimately do important things, although people who work with doors closed often work harder. Somehow ✲ they seem to work on slightly the wrong thing - not much, but enough that they miss fame.
