Keeping your files backed up and in order is a lot of work and I find it easy to put off the task to a later time.
But, today I'm going to back up my kindle books. I want to be able to read them, and more importantly share them in the future.
I'm glad that for most books that I really love I bought a hard copy AND the digital version.
Untangling myself from Amazon has been tricky. I used to shop on there every week. No longer. I still listen to some audible books but I'm phasing that out.
