watch a video or two, than head out the street and do the same thing is not that simple, Eric has been done this for many years, he knows what is he doing.
anyway, are you street smart enough? when form a group and hit the street, if anyone of you get challenged by your subject, will the rest of you stood by him? or run away as fast as you could?
just take one baby step at a time, push yourself a little at a time, not every can do the same as Eric, if it is so easy, he don't have to go around to share his skills already.
