Misunderstood by outsiders and often misunderstood by children, especially adolescents’, parents sacrifice can bring them as much satisfaction or even more than what the children receive by their sacrifice. Putting your children first will benefit them in many ways especially later in life when they can come to understand your time, attention, resources, and love was given for their sake.
Selflessness is important for families to be happy. A balance must be met to prevent over-privileging children (e.g. spoiled) but the most simplistic gesture of love from parents comes from sacrifice of any kind.
