Most people can read more than one book during the same week. They read one a little bit, then the other, then back to the first one without losing track of where they are on each book. Some people can read several books at the same time like that. But I don’t think someone can read fifty books at the same time and still keep track of all of them. So there is some number that is the limit of how many books you can handle simultaneously. Similarly there is a number of relationships each person can handle, and it varies from person to person.
If you are reading different books they don’t have to be necessarily about the same subject. If one book is about politics for instance, the other books don’t need to be about politics as well. You can be reading one book about cooking, another about photography, one about dieting, another about computers, and so on. Similarly humans maintain relationships of different natures simultaneously. Different people play different roles in your life. But even within the somewhat narrower range of romantic and sexual relationships you can be having different types of relationships at the same time.
Some books you read in a day, during one long flight, or during a weekend. You like them for the short term and entertainment you get from them. Other books are big novels and you want to read them for a long period of time. Some books are references and you like to just go back to them every now and them when you feel the need.
When you finish reading a book don’t just drop it anywhere or leave it laying around out of place. Put it back on the shelf! Unfold the corners, make sure the cover is fine and remove page markers. Put it back on the shelf in good shape and with respect. The other books will see that is the way you treat a book and they will appreciate you more for that!
Every time you read a book it makes you smarter and more experienced, more prepared to read the next book that comes along. That is why it’s important to always read something. Even if you don’t have right now the exact book you would like to find, but there is a book of quality within reach and you have the opportunity, read it anyway for the experience it will give you.
Finally, it doesn’t matter how many times you read a book, the ending will still be the same.
