I remember, as I used to give lessons to the president of the company, who wanted to tidy up his office. Its shelves were filled with titles with complicated names, what can be expected from the president of the company, from classics such as Druckner and Carnegie, to the latest bestsellers. I felt, as if I walked into a bookstore. At the sight of his collection, I had a bad feeling. When he started sorting his book collection, shoved a lot of books into a pile of "retainable", declaring, that he hasn't read them yet. When he finished, he still had 50 position, and the collection has only shrunk a little. When I asked him, why is he holding them, he gave me the classic from my list of most likely answers: "Because I would like to read it someday". Based on my personal experience, I can answer that right away, that "someday" never comes.
If you missed an opportunity to read a book, when someone recommended it to you or it's a book, which you have been going to read for a long time, time to let go. Maybe when you bought it, you were sincerely going to read it, but if you haven't done it so far, it means, that this book was supposed to show you, that you don't need it. There is also no reason to end half-read books. Apparently they were only to be read partially. Get rid of unread books. It will be much better, if you read this book, which gets your attention now, than this, which has been covered with dust for years.
The holders of large collections are also mostly diligent learners. Hence, I see so many encyclopedias and textbooks on my clients' shelves. You can list here the entire spectrum of textbooks and guides on accounting, by philosophy, computer manuals for aromatherapy and painting. Sometimes I am amazed by the kind of skill, what my clients are interested in. Many of them also keep old school textbooks and period notebooks, when they learned to write.
If there are copies in your book collection, which fall into this category, nalegam, to let you drop the thought, that you will use them someday and she got rid of them today. Why? Because there is little chance, that you will ever reach for them. Less than 15 percent of my clients use such books. When they explain, why their attachment to such books, they usually talk about it, that "one day" they will reach for it. "I'd like to study it sometime", “I'll learn it, when I will have a little more time ", "I thought, that it will be useful to me in learning English ", “I wanted to master the basics of accounting, because I work in management ". If you haven't realized your idea yet, then throw this book away. Only by getting rid of the book, you will be able to tell, how much you care about the topic. If your intentions haven't changed after you kicked her out, means, that you had a good feeling. If, after throwing away the book, you care so much about it, that you will want to buy it – do it, but read it this time.
