I would probably go with #3, because I know that ANYONE can get their ass kicked. At least in terms of attitude and philosophy that is a safe road to take. That way your EGO doesn't overly inflated and you begin walking around with an exaggerated sense of your own "deadliness".
I've seen overly confident people have their asses handed to them too many times and I just know better all too well.
This attitude makes me a nice guy to be around, which of course goes a long way toward keeping me out of any possible trouble that might be avoided to begin with.
