>> Most times, when I’ve tried to learn a programming technology without a concrete goal to get something built, it is hard for me to maintain interest I feel the same way. However, I take it one step further. I lose interest after I create the one core feature that drew me to the project. I've made shoot em ups before, but I wanted to do one with enemies that flew in like Galaga. After I replicated the first few patterns, I lost interest. You couldn't even shoot the enemies, but I already knew how to do that.
