You hate feeling like you're in the dark. If you lack critical knowledge, take a course. It will take time to grasp elusive concepts, so be patient. When you have questions, save them for the end of the session. Interrupting your teacher will cause resentment, both from the instructors and your fellow students. A good rule of thumb to follow in the classroom is to listen more than you speak. Eventually, the knowledge you seek will start taking root. At that point, your frustration will give way to relief.
