Have you guys learned any life lessons from the show?

I have learned many things, but the one thing that I've taken from the show the most is the value of friendship.
In the past, I was a bad friend, if they even considered me a friend. I would lie to them, talk behind their back, steal from them, put them down to make myself feel superior, etc.

Now that I look at it, I was more of a bully than a friend. The show taught me to cherish and respect those around me, not just friends, but family, and strangers too.

I've done some bad things when I was younger, that I have regretted of doing for the longest time. The show has taught me to forgive myself, and not only place the past behind me, but also learn from those mistakes, and look toward the future with a smile.

Now that I've told a little of what I've learned, tell me what you have.
