In 1979, graduates of the MBA program were asked to set clear written goals for their future and their plans to accomplish them. It turned out only 3 percent of the graduates had written goals, 13 percent had goals but they were not in writing and 84 percent had no specific goals at all–aside from getting out of school and enjoying the summer.
Ten years later, in 1989, the researchers again interviewed the members of that same graduating class. They found that the 13 percent who had goals that were not in writing were earning, on average, twice as much as the 84 percent of students who had no goals at all. Most surprisingly, they found that the 3 percent of graduates who had clear, written goals were earning, on average, 10 times more than 97 percent of their graduating class. The only difference between the groups was the clarity of goals they had set (and spelled out) for themselves when they graduated.
