Social Recalibration - Compassion.

So you arrive at the place, where you see other person suffering the same thing you were suffering. And there is no selfishness your heart will filled with compassion.

It can not be a thought but an emotion. A thought will make you look at the other person with the eyes of pitty. Compassion will fill your heart with love.

You can practice compassion and sharing but the moment someone you help becomes ungrateful that will make you feel bad. Although that is the most oblivious expectations.
