ego in moderation is necessary, without it,
you dont compete for the best for yourself,
leading to good food, shelter, knowledge,
partner, health, comfort, convinience and
hence and overall good life. All the
necessary thing in life is attached with
pleasure which leads to it like taste pleasure
with food, sexual pleasure with
reproduction. so that in concious world we
seek for it. Ego works in a way that you
want pleasure once you feel it and that to
better one if there is a choice. thats how
nature wanted it to be. You should try for
the best. Thats what nature/god want you
to do.
