The brain registers the negative quicker and retains it longer; this is the human brain. Positive may appeal but it slips off soon. That is the reason with millions of good things in life people grope in the dark lanes of dark memories and feel depressed that compared to others their life is not as good. First thank God for every little good thing that has happened since childhood, and affirm that your present state is what is exactly needed to reach the next step of the ladder of life. See the higher intention of God’s intelligence, that God loves you as you are. Give that love to all you meet. But remain detached, human love brings pain, next step of ladder is to love God, it would only bring quiet and peace, joy and silence.
