You want to charge off and change the world.  Can you do it in one day?  It took Someone else seven days to create
it.  Relax.  You have a lifetime and then some to change
just one person, and you are that one. 
As you change, so do those around you, but do not even worry about
others.  Yes, help others.  Yes, teach, and serve, and please, and calm,
and cheer, and encourage others as the opportunities arise and as you are
guided to do so.  But focus first on the
self.

All are aspects of the One.  As
the one known as you learns to love fully, you are better prepared to help
others.  What do they teach you on your
airlines?  Put the oxygen mask over your
own mouth first so that you can help others. 
Take in a deep breath now and relax. 
You have all of eternity to heal.
