2. Don't shave over the same spot many times. If you have to constantly shave over the same spot, get a new blade.
3. Don't go against the grain. Again, this will cut the hairs to short, and skin will grow over.
4. Don't touch your face (or other shaved area) with your hands. Your hands are the dirtiest part of your body, keep them away from your face.

Pretty simple.
