Now that you’ve thought about events, pre-orders, publicity, and on-sale date, how can you actually keep track of your sales? One of the best tools is Amazon Author Central. You need to sign up for that service, which is free, way in advance of your on-sale date. But once you do, you can add additional information to your book’s product page. There you can see your BookScan numbers and your Amazon sales. Keep in mind that BookScan numbers lag but Amazon has real time access to Amazon data. Your publisher can usually get you real time access to ebook sales. Also you can get your sales numbers from the stores where you’ve done events. Add them up and you’ll have a good indication of how you’re doing.

Making no challenge to the muscles, such as do not increase the lifting weight, or the number of times for a training set will make your muscles remains their current size. Therefore, you should always challenge yourself and your muscle mass with new, harder levels with different training programs, so your muscle muss will have the opportunity to grow bigger and stronger.
