Maybe I am overstating a little, but all the works we see as great required staying power. Apollo was a ten year program. The Manhattan Project took 6 years to develop the bomb. Firefox took 2 years to exit beta, and the iPod took several years to pick up steam. and Tesla has been going 12 years, Space X 13. It's not that you achieve nothing in a year tenure, but can you really accomplish anything great? Can you think of any good examples of people who showed up January 1st, changed the world, and left by Christmas?
