The first thing is don't worry about having to read the classics right away. They are something that every person should read at some point in their life and they may take a good long while too. So the first thing is to relax. Pick something you like and jump right in.
The most important thing you need to know before starting your reading adventure is what you want to read. You have probably heard people tell you this advice many times, but it's true. It doesn't help if you're starting a book but hate what it's about or how it's written. There are so many books out there, and even though the digital age allows you to read some of them free of charge, there are still some that may cost a little bit of money, which means that if you don't like them (or don't finish them), then it was money spent for nothing.
