There are some things in life that you just have to experience in order to fully appreciate the importance of certain events or circumstances.
The perfect example of this is drug addiction. I am an addict, and I am constantly amazed at how no one can really understand what I'm going through unless they themselves have been through it. All the counselors, psychiatrists, police officers, friends, family, etc couldn't understand why I did the things I did to support my habit.
Which begs the question: Is experience a much more valuable tool than simple education? In Elementary school I completed the D.A.R.E. program with a B+ but it didn't teach me the life lessons that desperate drug abuse did.
The transformation I underwent due to abusing drugs was something I don't think I could have been taught or realized simply by living life. I was very spoiled and self-centered. Addiction taught me how to be humble and truly appreciate the things you have.
But the most important thing it taught me? Empathy. Being able to sympathize with people from all situations and walks of life and not having the smug feeling that I'm better than anyone.
I can walk into an Alcoholics Anonymous or Narcotics Anonymous meeting and every single person in that room will understand what I'm going through.
Being aware and on guard 24/7 is something I will have to do for the rest of my life. I have to watch out for the subtle thought patterns and behaviors that will sneak up on me and cause me to relapse in a second. And then leave me wondering what the hell happened when I come to.
