What we want from others can only be as much as we are prepared to give and we have to be prepared to be that person first without any condition or attaching anything to our actions.
If we want more love we have to be love
If we want more kindness we have to be kindness.
If we want more empathy we have to be empathetic.
We have these expectations of others which we could choose to have none and then there can not be disappointment.
What we give out will come back. We have to be the light and example not simply expect it from others.
