I love reading books. But whenever I buy one I no longer keep them. Either I give them or lend them to someone else.
If I read a book and keep it, there is little chance that I will get the same book and read it again. I might never touch it again. It will just be on the shelf gathering dust.
But if I give it away or lend it to another reader, the book will have a new life.
The book has inspired me and it will inspire another.
Lucky is that book to have served its purpose more than once.
