The "iron prescription"................

"Whenever you think that some situation or some person is ruining your life, it is actually you who are ruining your life.  It is such a simple idea.  Feeling like a victim is a perfectly disastrous way to go through life.  If you just take the attitude that however bad it is in any way, it's always your fault and you just fix it the best you can - the so-called "iron prescription" - I think that really works."
-Charlie Munger
