I found that picking up a few books on electronics/robotics really helped me learn. At first I would look at a circuit and have absolutely no idea how it worked or even what most of the components were or did. The more I read the more I became familiar with basic circuit design. One book that really helped me was "Getting Started In Electronics" from Radio Shack. Granted, its format seems a bit aimed towards children (12 years old maybe) but it has a lot of important and fundamental information about different electronic devices. I have also bought books specific to the PIC micros such as Easy Pic'n, Programming and Customizing Pic Micros, Pic'n Up the Pace, and Programming Robot Controllers. Robot books I have include Robot Builders Bonanza, Build Your Own Robot (mainly geared towards the Motorola 68hc11/12 micro), and Robots, Androids, and Animatronics. I have also spent countless hours reading anything and everything I can find on the net. But now, to show for all my work, I can look at a circuit and have a good understanding of what each part of the circuit does and the general reasoning behind it. Just keep at it, don't get discouraged, and read a lot :) It doesn't matter if you understand something today because something you read tomorrow might put it into perspective and it will all come together.
