You may worry that you do not read fast enough to keep up with your academic work. It's important, when reading, to remember that efficiency is a more useful goal than speed. If you read something very quickly, but don't remember most of it, are not able to apply it, or can't connect it to other readings, then you are not being efficient.
When your purposes for reading make it appropriate to read deeply—you want to be able to follow the argument, to discuss it with your classmates, to critique it in a paper, or you need to be able to remember the material for a test—you will probably want to read a text more than once.
