I've been fiddling around with it for about a year and I still have problems doing stuff lol.

What version is it?
Get in to your library and get a book so you can sit down with it on your lap in front of the PC and work through stuff.
There is also a great help section and if you google photoshop tutorials you will find heaps out there. It's just a matter of spending the time to practice it.

eg if you want to learn how to remove red eye then put into google "photoshop red eye removal tutorial" and there will be stacks of online stuff.

Yesterday I was determined to make a watermark for my photos and I found both how to make one and then how to make it an action from an online tutorial
