Don't pack it in just yet :) I'm a person of little patience and am a slow learner when it comes to Poser. It takes me awhile to learn any program actually. That's just the way it is for me. Take it one program at a time. Work with Poser, learn it. Then move into making textures. Then start in with dabbling into the 3D programs to make models. As people keep telling me, slow down and learn to crawl before you walk, and walk before you run. There aren't any good books about Poser on the market. But Dr. Geep has some good tutorials. You just need to keep working through tutorials that you find, some more than once while working with a different object using different settings etc in order to get the hang of the dials and buttons and stuff. These programs aren't easy, at least for me they aren't. But don't give up. There are lots of people here that can help you... and me... and anyone else who is new, or newer, to learn. Just pick one program to work with instead of trying to figure them all out at once. You have sensory overload and are feeling overwhelmed and probably a whole lot confused.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
