The trick with photoshop is to use it only to enhance your images.
Photoshop is such a remarkably deep application that you can spend a lifetime playing with it! It’s almost too much for a novice to enjoy using.
I would recommend getting yourself some software that is easier to learn and use.
What do you use to manage your photographs?
Have you tried playing around with Picasa? (free application)
http://picasa.google.com/
If you just want to do simple improvements on your images like cropping, fixing color and contrast picasa is good.
If you want something more advanced I would get Adobe Lightroom.
I use lightroom for all my stuff. It’s like all the stuff you would use photoshop for but optimized for photography.
It’s really incredible.
If there is something specific you want to learn in photoshop let me know.
