"Most of all, side project successes serve as a reminder that when you try more stuff than the next guy, up go the odds that you are going to do something right. It is the law of large numbers in entrepreneurship. Thomas Jefferson once wrote, “It is amazing how much may be done if we are always doing.” And as Jefferson later learned, it is amazing what can come of some of the things we least expect, which is good reason to always keep that crackpot project bubbling on the side and to stay open-minded about what it might one day become."
