This is easy. You like Eddie Van Halen. Who did he listen to? Who are his influences? Cream. So you pick up Disraeli Gears and like Eric Clapton. Who did he listen to? Who are his influences? The Three Kings: Albert, Freddie and B.B. Which leads to Elmore James and Robert Johnson.
Congratulations. You now have the same influences that everyone who ever bought an issue of Guitar World has.
Of course, it's good to listen to Van Halen and pick out what you can. Of course Eric Clapton's important. Of course B.B. King is great. Of course, Robert Johnson is just awesome. I'm not arguing against them.
I am arguing for a variety of influence. X is punk rock with Carter Family harmonies. Lee Roy Parnell is straight blues, but he's out of Nashville so he's Country. Clarence White (yes, I have to mention him) brought Country picking into Rock. John Five is bringing Hank Garland to a generation of young shredders.
So, listen to people outside your style. Integrate it. It'll help you not suck, and it might just help you out of a jam.
