I love a good paperback/hardback book - the feel, the smells, there's nothing like a real book. But I do feel that Kindle and ebooks have opened up opportunities for new readers. They've reduced the cost of books and made them more accessible. I believe so many more people read today because of the convenience of the ebook.
More often than I like currently. My advice, at least what works for me, is to walk away from the writing for a while. Don't force it. Put it aside for a day or two, or a month if you can. Listen to music, watch movies, whatever inspires you. The ideas will begin to flow again on their own.
