Well first off, you can't force yourself to enjoy reading. It comes naturally. But you can help find your inner reader by determining YOUR genre of books. Your age definitely matters in this case, because it's not likely a teenage girl will enjoy a book such as "D-Day" by Antony Beevor(WW2 occurence when Allied forces invaded France on Normandy, etc. etc.) or The Giving Tree by Shel Silverstein(child's book about a tree who gives this little boy anything on her that he may need etc. etc.). And maybe some teen girls do enjoy either of those. D-Day would be more geared toward a history buff out of college or retired, and The Giving Tree might be more for six year olds or so.
Check out barnesandnoble.com . They have many book choices.
Or:
see what kinds of movies you like:
Romance, Horror, Non-fiction, Comedy, Documentary, Action, Adventure, Animated, etc.
And try a shorter book in that genre. But trust me; if it is a good book, length won't matter at all! I remember one book I read that was about 800 pages, and I was so upset that it was over! I wanted it to be longer because it was so good!
Also, we don't really know your daily schedule, so we couldn't really help you there. But, if you are a school student, finish up homework in a class, and bring your book in there to read in your free time. Working? Read before you go to bed. When I was younger, my parents would always come into my room and take the book off my face so I wouldn't suffocate while I slept! I fall asleep reading, and I read in the mornings! If you don't drive to school/work and don't get carsick, read then! Set a goal for yourself: aim for maybe a chapter a night, or a chapter a week, or even five chapters a night. It all depends on how busy you are.
If you tell me more about you : age range, preferred movie type, schedule, etc. and e-mail me, I'd be happy to try and help you find a book! But if you prefer not, check out barnes and noble (store), and scan the shelves. If a book has an attractive/appealing cover, pick it up and read the back. If it sounds interesting, write down the name and first see if you can borrow it at a library or if a friend owns it just in case you end up not liking it. If you do enjoy it and would want to read it again, go ahead and buy it! Barnes and Noble or Borders will soon be your best friend!
