" Changing the world "
Sounds impossible?
Right. It may take a long while.
However, " changing yourself " should not be
that difficult because you don't need to deal
with anyone except yourself.
It's all yourself that you must work on.
" Changing yourself " is actually the most
important key to open the door to everything
you need to do for " changing the world ".
I'd say that without changing yourself,
the world would not change.
