Many times. Sometimes purposefully, other times without trying by just saying my thoughts passively about something. When I have friends they tend to seek me for advice, even when I tell them I might not be the best person for it (especially when it's guy friends wanting advice on how to get girls - I'm not a typical girl and thus can't give typical advice there). Typically when I have influenced others it goes well, but sometimes not so much. I can't recall any specific examples, but I'll say that's a good thing because I tend to only remember bad things...
