Many times people long for good lifestyles of friends or neighbours . It saddens them to struggle to keep up. Note that Life is not a race course. If your friend is succeeding in any sphere of life, don’t be envious but create yours. If you can’t build a mansion; create a home and be happy. Your home is your castle no matter how tattered it may look.
