Reading is an important skill that all parents need to encourage their children to master. A person who can read, and read well, is more likely to:
graduate from college;
get a higher paying job;
experience the joys of learning new things;
and enjoy the stress-reducing entertainment of a good book.
While it can be harder to turn a teen on to reading than say, a 3-year-old who loves the attention you give when you read him/her a book, it is not anywhere near impossible.
