I suspect I don't come across all that well. I often catch myself mid conversation and think 'urgh, Shut up, they don't want to hear about you'.
I think I either talk to much, don't talk enough, say the wrong thing, don't sound like an adult, get hung up on things that others find boring...or find very tenuous links in conversation and go off on stupid tangents.
I think I probably come across as trying too hard, probably because I do.
