Dear Colmachine, welcome to Medium. I wish you great success on the platform. Your pledge to have an open mind will serve you well. I'm hardly an expert here, but I have made enough mistakes to have learned a few lessons. Might I offer two pieces of advice since you would like some monetary success here?
1. ALWAYS post a picture with your article. You can find instructions on how to do that or leave me a message on one of my articles and I will walk you through it. Very simple. You just won't get readers without it.
2. Put a photo in your profile. Many readers won't read someone without a photo or who isn't a member because we're leery of spammers. If you want to keep your identity a secret you can post a vector or symbol but put something there. It shows your serious.
3. Read other writers (shoot for 20 a day but as many as you can) and follow them and comment on their articles.
So three tips. They should get you started. Good luck.
