I have milked this one to death. Honestly, I have written so much about this one life changing moment in my life that if I write anything more about it the meaning will start to recede. Just to know what I am referencing it is when my girlfriend broke up with me during freshman year of college. It caused the largest overall change to myself and my personality. In essence it thrust me into adulthood. You will find PLENTY of posts about this either directly or tangentially. I do encourage you to check them out.
