It is an old phrase, but a very true one.
What we put out to the world is what we will get back.
If we want more kindness, be more kind.
If we want more love, then we need to be more loving.
If we want anything, we have to be the ones to give.
The moment we expect things from others is the moment that we are focusing on controlling others and not on ourselves.
The only thing we can control is what we do.
