Each of us makes hundreds of choices every day. Most of them are so mundane and ordinary that they become automatic like breathing. What we eat for breakfast, what we wear, what way we go to work, what bills we pay and what bills we are postponing. What programs we watch on TV, what we do at work, how we greet a friend and how the enemy. We don't remember any of these choices for more than an hour.

But there are other choices we need to make from time to time. We can later look back at these decisions and remember them with bitter regret or with triumphant joy, depending on how they affected our lives.

These momentous turning points are rarely planned or expected. How could they be like that, since the vast majority of people walk through life without any point, destination or even a map?
