Learning Photoshop. Been meaning to for a long time. I've tinkered for years, but now I'm learning the really cool (powerful, creative) stuff.
At one time, Photoshop was "the killer app" ยป a reason in itself to buy a computer (Mac). And the more I learn, the easier it is to see why. (It lets you do way-cool things .. with graphics and photos.)
Over the years Photoshop has grown complex, somewhat beastly, difficult to tame. These days, learning to wield its magic takes a commitment. (As I'm finding.)
I had really wanted to wade into some server-side scripting and database management, but that requires even more of a commitment. Been too distracted for that. (Tho it's still on my list.)
Now however, I'm glad I went the Photoshop route. Everybody I've told says, "Yeah, I wanna learn Photoshop, too."
(And once someone knows it, they'll always know it.)
