פרקי אבות
First a person must think that he/she is SOOO important that the whole world was created just for them. אם אין אני לי מי - First I have to be for myself and have הגבהת הלב - an elevated heart.
Then I have to immediately get a sense of perspective וכשאני לעצמי מה אני - a broken heart, a realization of the context in which I find myself. A world where I am so small and irrelevant, where if I want to have lasting value I must help others achieve their goals and FORGET about myself.
However one may not have a broken heart all day long, just a little in order to maintain perspective.
