Without love, life becomes barren and fruitless but with love it grows and flourishes. Love is a two-way thing, a giving and receiving. Never sit there expecting to be loved without giving love. The more love you pour out the more you will receive. So when you feel the lack of love, look within yourselves and see where and how you can love more and as you do something about it, love will come pouring in filling your whole life and then going out and out into the lives of others.
Shoulder your responsibilities and cease looking at the other people expecting them to change. Do something about it and start with yourself. Put your own house in order and see what happens.
