LOL! At one time I spent about 10 hours a day in Photoshop, taught a bit, and I have probably a decade invested learning it so don't feel bad. Now most of what I do is 'shop something onto a car, or trace a logo for someone. It's amazing what you forget, but it's a lot more fun this way
I know the feeling. I used AutoCAD everyday in construction years ago, couldn't trek you how to add a new line now if my life depended on it, lol.
