of people in this world:
one, the selfish; and
two, the selfless.
the selfish do things for himself.
his priority is himself.
he can be anything,
in order to achieve what he wants.
if what he does helps others, too;
then, that’s merely a plus.
the selfless do things for others.
his priority is the other.
if what he does helps him, also;
then, that is only a bonus.
