pally buff macro

I found this post. Its about 2 years old but I like it. The macro

/targetparty
/cast blessing of wisdom

works but does not buff the pally giving the buff just everyone else. So if you have 4 pallys the person giving wisdom does not get it but everyone else does.

I am not a real big add-on guy so i like it. Any one think they can rewrite it so that ther person giving it gets the buff too ?
