Okay, so I will try to keep this as short as possible. Long story short, I find four-leaf clovers ALL THE TIME!
Like, one day I found 30 of them in one patch. Now since I find these four leaf clovers SO OFTEN, I personally believe they are better luck for me if I give them away. One time, I was out walking around with my brother @justinashby and I had just found a patch with about half a dozen of these mutant clovers. So I walked towards the local grocery store to find some random people to give them away to. I saw this girl sitting in front of the store crying. She didn't look so well, dirty tattered cloths, she looked homeless. I took it upon myself to try to cheer her up, so I walked up to her, handed her the best looking clover I had just found and said "Excuse me, miss, but you are ENTIRELY too pretty to be sitting here crying in public". She thanked me, stopped crying, and I went about my day.
About a year later, I was at the local mall, and this girl comes running up to me out of no where yelling "It's you! You're Him!!" and wraps me up in a big, very friendly hug! I hugged her back (cute, random girls don't come up out of no where and hug you every day) and asked her where I knew her from. She told me that I was the guy that had given her the four leaf clover and that I had saved her life. Turns out, she was sitting in front of that store crying, debating taking her own life. She had just gotten out of a very abusive relationship, and had been told repeatedly by her ex all manner of nasty things. "You're ugly. You're worthless" et-cetera. It was no surprise that I didn't recognize her. She was wearing much nicer cloths, almost business casual, had her make-up done all nice, and did not look like the same street mouse I had met the year before. She told me that it was my gesture of giving her the clover and a compliment that saved her life. I convinced her, with just a couple words, that the world was not ALL bad, and maybe there were things worth living for. To me, it was a very small gesture, but to her, it was life changing, literally. I am not sure if this counts as a "success story", but I totally count it as a success. I had no idea that it would be such a huge impact on someone, but it really made me feel good to know that I had affected someone in such a POSITIVE way!
Sorry, probably way more than 100 words, but there is my success story.
