I self-published a Book via Amazon KDP

I started in 2019 and started writing my notes using Scrivener - and during lockdown 2020 started doing design work and InDesign layouts.
The journey to self-publish is well worth it, learning the process and the challenges of writing (and editing) and the context switching that goes with it.

Sadly, in the world of smartphones books are like startups - you need a community to sell too to get traction - as a side note, apparently, when it comes to Amazon KDP - you need about 6-7 books before you can get traction in amazon's marketplace.
