I don't know. I hope that the more positive interactions I have had with ppl along the way have made a difference. I hope that somehow I have helped someone to feel better, whether it be on here or elsewhere. I hope that with my happiness blog, I am making a difference somehow in people's lives. I worked with abused and violent male teens in a locked facility years ago. I hope that somehow I may have made a positive difference for at least some of them, if not, just maybe one. It's hard to know when you don't ever see someone again. It's easier to know with your own friends. PC has made a big difference in my own life, generally and overall.
