Indiscriminate kindness.

 

  Negative experiences usually succeed in driving us to register our protest against them. You have bad service at a restaurant, or the car in front of you is too slow, or you hate how a place works, it will usually occur to you to register a complaint or express your frustration.

  Positive experiences usually don't drive you to acknowledge them as ardently. Some of it is how our attention works, and some of it is beyond our control. We can react to accidents but not to accidents prevented.

Furthermore, when someone looks happy or it appears that they are doing well in life, there is a feeling in me that they are already surrounded by positive reinforcement, and they don't need my feedback as much as someone in overt grief does. But that's not true. Sometimes the people who appear to be doing very well are one step away from collapsing into a dungeon of psychological hell and our acknowledgement of the way in which they are valuable, can help them see what they are not seeing. (Have you never lived in a way that everything about you appeared okay but you were broken inside? Almost everyone has)

 I remember every single kind word said to me by anyone in my life. Some of the words came when I was surrounded by pitch-black darkness and they worked as the single ray of light that illuminated what I was not seeing.

  I feel that kindness be indiscriminate. You cannot accurately estimate who doesn't need it. 

Apart from that, just as your attention falls on things which are wrong and which should be rightfully pointed out because that's how change comes, if it falls on the good things and you acknowledge them, they may feel validated to exist and grow.
