It's not for everyone. Some people are more receptive to a "tough love" approach to self help or life advice.

You make a good point but, unfortunately my favorite author is long dead so I won’t be getting a signed copy of anything any time soon hahaha. But collectors editions or other unique versions of material is a great way to encourage someone to buy a physical copy.

I live in a small space though so my Kindle Oasis is really great for me, it’s addicting having so many books so easily accessible on such a high quality device.
