I think I must have mentioned it in the past, but please excuse me for reiterating : Every reader (of my book) counts.
In March and April, I have sold one copy of my book each month via Amazon. I am happy about it as I appreciate every copy and reader. I am inferring that 2 people are interested in the subject of adult learning and my opinions and thus have bought my book. For that, I am pleased and one person (one copy) at a time!
