Sometimes just getting started is the hardest part! Here are some strategies.
Just commit to reading, say, the first 50 pages or first few chapters - or listen to the first hour of an audiobook. If it's a good fit for you, you'll want to keep going. And if it's not - feel free to ditch it and try something else!
Think about what sort of a book you want. Is there a particular genre you like or want to try out, should it be short or long, funny or serious, etc.?
