An Epiphany.

Epiphany
defined: a sudden, intuitive perception of or insight into the reality or essential meaning of something, usually initiated by some simple, homely, or commonplace occurrence or experience.

I had an epiphany on the 1st August 2009 when i was in a place where i picked up a new toothbrush provided by the hotel's service.

I felt a strong sense of desire to help these children in Cambodia build a better life for themselves.

That was when i decided to take responsibility and action.
