This is an important question, since I would not be surprised, if many people are asking the same question. Here are a few reasons why I think literature is very important:
1. Literature challenges your mind to think. On the most fundamental level, it exercises your mind. You grow in intelligence. This is reason enough to read.
2. Literature opens your mind to look at things from a different perspective. If you don't read, the fact is that you will be narrow in your thinking. In a world that is global, reading enables you to appreciate more and look at things from other people's points of view.
3. Literature also enable you to enter into different worlds. You can experience new things and these things can shape your life and make you into a better person.
