Street Photography

So I'm really wondering if I have it in me to try street photography.  I've always been told I have a natural ability to talk to anybody and it's true, I really can talk to just about anyone.  I don't know how I do it necessarily but I think I just pick out something about them to mention and then try to start a conversation built on that.  It could also just simply be an "excuse me, do you mind if I sit here?" and from there talk about whatever I see.  Anyway, I'm wondering if I have the chutzpah to pull it off.  Talking to someone and then asking them to let me take their photo is two entirely different things.  I remember watching a video of Jimmy Hickey regarding how to start doing street photography and it got me interested.  So now I just need to find a way to translate my "gift of gab" into "just shoot."  Stay tuned....
