4. Reading aloud: Spend 10 to 15 minutes reading aloud. Let the concepts from each sentence sink into your mind in an ordered and cadenced manner. Don’t feel bad if you need to reread the paragraph for the concept to become part of you. Remember: if you cannot explain it, you really don’t know it. This practice not only helps you retain what you read, but it increases your attention span, which may have been damaged by multitasking.
