Shipping. You will only have a few days to ship a book after it sells, and even less time if you agree to include two-day or overnight shipping as part of your options. And since you’ll want to save as much as you can on the shipping, you’ll have to devise a plan. Many people set aside specific days for shipping – say 3 days a week – and then make one big trip to the post office. As long as there isn’t anything else in the package, you can send books via media mail, which is the least expensive option. Finally, your books will need to be packaged in a way that they won’t get damaged in transit.
Google has a few different options for expanding YouTube. One is a monthly subscription to view an ad-free version of YouTube with additional exclusive videos that non-paying users can’t access. In Autumn 2015 the company rolled out YouTube Red — a subscription service that allows watching ad-free videos and listen to music without interruptions for $9.99 a month. YouTube Red that was probably intended as a competitor to Netflix, also includes original shows and movies. Around the same time, the company launched YouTube music app, which is free with ads, but offers an enhanced music experience if a consumer is simultaneously subscribed to YouTube Red.

Typically only offered to large YouTube channels with a wide audience (although not exclusively), another big way to earn cash through YouTube is to get sponsored deals with companies that will pay you to promote or mention their products in your videos. You can earn money this way either as a lump sum of cash the company will pay you for the deal, clicks on the company's link, or on a per-view basis. 
Great article on Internet marketing. A key ingredient in the whole marketing process is the passion or purpose for which one is marketing.

Most people never do enough self evaluation and soul searching to discover what they are here on this earth for.
How much will you make? I think my best month with Google AdSense was almost $5,000 over the last ten years. That amazing month blew my mind since it was actually near the beginning of my blogging journey. When you go from making zero to $5,000 in a month, that will rock your world. For me, it also got me even more excited because I knew there were other ways to monetize.
