This was in a facebook group and I found it interesting, dunno if Yoko Ono actually said it but I don't doubt it:
"I read on a website today something Yoko Ono said
1. Try to say nothing negative about anybody.
a) for three days
b) for forty-five days
c) for three months
See what happens to your life."

I couldn't do it. I wish I could, I really do. It is pathetic how many of my conversations include complaints about people. Even if I tried, I am constantly surrounded by people who say negative things about others, and sometimes I do tell them to stfu (if it's really rude) but most of the time I just consider it venting, which is kind of necessary. & I am not saying I never start a conversation by complaining about someone, because I do.. it's like a silence filler for me, if I don't know what to say I complain - whether it's about school, people, clothes, anything. I hate the fact that I am like that. Anyway, just interested to see other people's thoughts.
