To develop attacking skills, might I suggest the method I myself employed to get myself out of a positionally based single dimensionality...
Play gambits. Once you start dropping pawns out of the opening, you are in essence forced to attack just to retain any real winning chances. In addition, it helps that, in most reputable gambits, the gambiter does gain significant attacking resources, especially when your opponent does not know the lines.
That and know the major tactical motifs.
Since PleaseSignHere____ has been posting random attacking games, I figure I'll go ahead and add to the mix.
Something thematic to consider from the following game: don't mix up passivity and defense. An advantage in development is something that can quickly become decisive, especially when your opponent is playing in a systemic fashion.
I didn't know that Fischer was known to have an attacking style. I've heard that his win percentage was quite high with the King's Gambit. Please direct me to a few of his best attacking games. Thanks.

Rigamagician: since you're posting GM games, why not give a shot out to your thematic namesake?
Maybe being a public school music teacher for so long has turned me into a touchy feely nice guy. This is not conducive to agressive, attacking chess.
Perhaps this is indeed true...and I note a certain irony here as well. Such an environment may well promote an access of niceness in teachers, but I remember high school (and especially junior high) as being a time of well-nigh unbridled savagery among students.
At any rate, it seems to me that your goal will require a substantial transformation. Right now your chess persona is perhaps uncomfortably close to this:
What you want it to end up being like is this:
Dirty Harry is my hero. Who is that fruit loops guy?

This is truly known as the game of the century? How ever it stands in chess history, dang, I never saw Bobby Fischer go on such a vicious attack before, but I've only seen a handful of his games. I've seen several games of his where he plays simple classical chess and you just know he has the other guy beat. It's so cool.
I wish he didn't go nuts. If his mental health had not gone south, I do believe he would have been regarded as the best chess player ever, with no arguments. Guys like that only come around once every few centuries.
Awesome attacking game. Thank you! 
Why be scared?
This is one place where you can jump in boots and all, without it costing you a cent!
Don't let ratings stop you from enjoying the game. Who cares if the parachute doesn't open, the ground is only a virtual environment anyway!
