I havea 12x12 intuos 2 Tablet (it's a little too big I think, but it works) and I use a program called Paintchat. I use a mouse sometimes to do sketches or warm up, because optic mouses can do different lines then my tablet can. I use them both. Most of those are just a few minutes.

Anyone can have the willpower if they're determined enough. It's all in the mind.
