Book on Holistic Health

Hello folks, need your opinion here. I work in the Tech industry here in south of Sweden. So of course not a medic but been listening to various spiritual teaching (Vethathiri Maharishi, Sadhguru, Dr BM Hegde etc ) and holistic healing methods for almost 10 year now. I'm myself medication-free for over a decade (not even a Paracetamol) and never fallen sick. I was speaking to my colleague the other day and told him that I have this feeling of fearlessness that I'm not going to fall sick and I know it. He found it hard to believe but that's understandable. Won't it be nice if everyone feels this way?

Anyway I have put all these thoughts in a book and explained some simple techniques that anyone can follow to reach to that state, because everyone can. Its in the final stages and hoping to finish in a 2 week's time. Was also thinking to reach out to some influencers to promote the book. But what does the community think of this idea considering the wellness market is already over-crowded? :-) Or am I just wasting my time? :-s
