To start off, I recommend that you get more practical-oriented books which contain lots of exercises. There are actually some books which try to explore discrete math using C or Mathematica/Maple. Those might make the subject a bit more interesting and concrete. I've found that (at least with computer books), for me the mindless visual quick-start texts are best to begin with. They make it more fun to explore the material even though the books have less "meat" for your buck. Even though I am advanced enough to sit down with a manual and understand it, these books are much more motivating for me.
