Every time I moved I sent all my hardback books to the Library. Now, at my age I no longer gather reading material to better myself or create new ideas. I have more than four thousand books, mostly fiction works on my hard drive backed up to the cloud via Dropbox. On top of this I have about 50 talking books which take somewhere between six and ten hours to listen to.
Your advice, Jon is well placed. Stick to it and continue to encourage your contemporaries to get the thoughts of others to stimulate their thinking.
