There is a goal setting story you can find in the material of many leading motivational speakers. The story goes that in 1953 the graduating class of Yale University were asked if they had clear, written goals.
3% did have written goals, 13% had goals which were not written down and the remaining 84% had no goals at all.
Twenty years later, at their class reunion, it was found thatthe 3% with written goals were worth more than the other 97% of their classmates!
You might conclude that goal setting is important!
You can also find plenty of people who claim that the story is an urban myth and that no such research ever took place!
Whatever you want to believe, it is obvious that you are likely to achieve more if you have clearly-defined goals than if you have no aim in mind.
