So, how can we achieve inner contentment? There are two methods. One method is to obtain everything that we want and desire—all the money, houses, and cars; the perfect mate; and the perfect body. The Dalai Lama has already pointed out the disadvantage of this approach; if our wants and desires remain unchecked, sooner or later we will run up against something that we want but can't have. The second, and more reliable, method is not to have what we want but rather to want and appreciate what we have.
