Imagine you are a cyclist. At the end of the 100 miles is a sweet, sweet piece of cake. But the road has uphills and downhills: the cognitive boosters and roadblocks. The optimist only sees the downhills. The pessimist only sees the uphills. The realist sees both, and makes a guess on whether this journey is worthwhile. Is the cake worth the effort? The optimist, while appealing, will soon be met with unexpected uphills. He will be distraught, and maybe even give up. Shoot for the realist, not the optimist.
