The self-publishing author dilemma

I always wanted to write a book and eventually, I found a way to orchestrate it and get published on Amazon. Now I am not going to lie, I was picking out my new penthouse apartment online and trying to make sure I would be safe in my poor neighborhood since I was going to wealthy and famous…then reality set in and my royalties started to almost disappear. Marketing feels like prostituting and pushing and pushing yourself on others and I have a problem with due to shame from my past. I still am very happy that I did write a memoir and I have another book I am releasing in about two weeks but if anyone has knowledge about RELIABLE MARKETING TACTICS please enlighten me because so far I am my own best customer in sales and I need exposure.
