Purpose

אלקי, עד שלא נוצרתי איני כדאי
ועכשיו שנוצרתי - כאילו לא נוצרתי.

"My God, before being created I was not worthy (?).
Now that I am created, it is as if I was not created."
(Yom Kippur shemoneh esreh, at the very end)

Meaning:
I was created for a purpose.
I was not worthy - I did not have a purpose (before being created).
It is as if I was not created - I have failed to fulfill my purpose.

(R' Kook)
