Getting into drawing,where do i start?

I personally have never heard of the "Drawing from the Right Side of the Brain" book, and I'm an art major, so I'm not sure how it'll help you, but if it has good reviews I say go for it! I personally prefer the book "Exploring the Basics of Drawing" by Victoria Vebell. It's a really comprehensive guide to how to start drawing and what materials you can use, and it's relatively inexpensive on Amazon. After that, look for tutorials on Deviant Art and Youtube, there's a lot of super helpful information there and you can get your questions answered. Starting with learning how to draw realistically is the best way to start. Drawing things from life with strengthen your foundation and serve you well throughout your entire art career if you decide to continue. However, before you move on to drawing in an anime/manga style, I highly recommend you develop your own style first, you'll find it much more useful to you than adopting a style that's not your own. If you decide to continue in art you'll gain more attention from work that's done in a style that's your own instead of one that belongs to someone or something else (which isn't to say your style can't have a base in anime/manga!). Best of luck!
