I think of book development like cooking spaghetti. There are many ways to cook it, but the basic ingredients should be present: The pasta, and the sauce, and the cheese topping! If you’re a fabulous cook, and you plan on selling spaghetti to earn extra income, it should be obvious to you that there are a lot of other places where it is sold, and you would have to convince people that your spaghetti is better than the others. You’d do this by making sure that the noodles are perfectly al dente, the sauce is tasty, and to give it an edge, you’d make it cheesier, put it in a nice container, and maybe add a sprig of parsley on top to add to the appeal. You wouldn’t serve it on the floor and tell people to go on and taste it because it’s truly delicious, and that you have slaved for many hours perfecting the taste.
Packaging and appearances are important, as much as the taste. In publishing, you could be the next great writer, but if you don’t present your words in the most appealing way possible, especially in this highly competitive industry, I doubt anyone would bother to read it except your friends and family, if at all.
