Too often in life we fall into the trap of placing our happiness on the attainment of a specific goal, object or result.   We attach our self worth to specific outcomes and if it doesn't turn out exactly that way, we allow ourselves to feel down, rather than appreciating the experience, learning from it or finding a suitable substitute.  Understanding how to avoid unhealthy attachment in life can be incredibly liberating, and actually help us achieve more of what we really want.
