Long lasting.

Goals are a means to an end, not the ultimate purpose of our lives. They are simply a tool to concentrate our focus and move us in a direction. The only reason we really pursue goals is to cause ourselves to expand and grow. Achieving goals by themselves will never make us happy in the long term; it's who you become, as you overcome the obstacles necessary to achieve your goals, that can give you the deepest of most long-lasting sense of fulfillment.
