Enjoyment, on the other hand, is not always pleasant, and it can be very stressful at times. A mountain climber, for example, may be close to freezing, utterly exhausted, and in danger of falling into a bottomless crevasse, yet he wouldn't want to be anywhere else. Sipping a piña colada under a palm tree at the edge of the turquoise ocean is idyllic, but it just doesn't compare to the exhilaration he feels on the windswept ridge.
