If you want to learn it, the key word is
learn. It's music. You learn it by listening to it. You can't listen if you're playing it first.
Listen. That's how you learned to talk, by listening to your parents, older siblings, people around the neighborhood, etc.
So it is with the Blues, Listen at clubs, to records(ok CD's or mpg's..) watch you tube. But listen. Then you start to copy what you heard. The more blues that you listen to, the more blues licks that you will hopefully add to your vocabulary. When you can sound like whomever, when ever, it will be because you listened to the greats enough, that you captured their soul. At some point, it will become your soul. You cannot repeat what you did not hear. You look like your parents because you have their genes. You will sound like your idols because you will have their genes too.....sort of. You only have two parents, but you can have many musical genes...that way you won't sound too much like one
parent

Just listen. When you become good, you'll even repeat stuff that you though you didn't like. That can be the curse..if there is one.
