If you want to awaken all of humanity then awaken all of yourself.
If you want to eliminate the suffering in the world, then eliminate all that is dark and negative in yourself.
Truly, the greatest gift you have to give is that of your own self-transformation.
--Lao Tzu

Practicing the Law of Giving is actually very simple:
If you want joy, give joy to others;
if you want love, learn to give love;
if you want attention and appreciation, learn to give attention and appreciation,
if you want material affluence, help others to become materially affluent.
In fact, the easiest way to get what you want is to help others get what they want. If you want to be blessed with all the good things in life, learn to silently bless everyone with all the good things in life.
