Stay away from "psychology". It is related to psychiatry and people that use them are "nuts"
Also your "negative traits" idea is bad. People with "negative traits" -
1) Don't recognize their problems
2) Don't care about their problems
3) Already know everything in the world
4) Are troublemakers and will cancel their sales.
5) And almost always have no money to spend to help themselves
Remember how to make money -
When you make people smart or make people rich.
Sometimes when you make them smart, they get rich.
So your niche is "self help" because people into "self help" are smart, beautiful and rich. At least that is what you are supposed to think when you take that Tony Robbins $20,000 mastermind weekend.....
Create a touchy-feely brand for the self-help niche.
Get the domain for it, install Wordpress on your "free CPanel web host"
Find a PLR club with several self help products on "self-help"
Here is a couple -
1 Percent Better Every Day
Unshakeable Confidence
Overcoming Anxiety
How To Develop Emotional Intelligence
Google and you will find them.
Use their sales pages as articles
Pull chapters from the ebooks and use them as articles.
Give away the courses to build your list or membership site.
Create an Amazon shop with cherry picked products in the self help niche, books, organic foods, health supplements, new age type clothing, crystals, salt lamps, aroma therapy, oils, etc.
Create a T-Shirt shop using your brand and one of the Print on Demand T-Shirt printers. See the articles on BHW about T-Shirts.
The money is in T-Shirts. Everyone can afford a T-Shirt.
To figure out the newest trends subscribe to trade magazines (usually free)
If you need to get an idea of "self help" sales copy, visit archive.org and search "GuruDAQ.com" It was still working in 2018. Look under "self help" and you will see the big names. Using a Gmail account and subscribe to all their sites. You will be avalanched with offers for their products. You can see how they sell products and get an idea of their sales funnels.
HIDE YOUR CREDIT CARD before reading those sales letters. They use NLP and advanced conversational hypnosis to sell their products. I kid you not. You have been warned.
If you want to be famous, cut your hair, remove the tatoos and wear a suit. Then take those PLR books and tweak/rewrite them to be your own product. Or go on Fiverr and get a ghostwriter to write a new 150-200 page "self help" book. Put your name on it, copyright it and print it on Lightning Source or Amazon Createspace.
NOW you are an "authority".
You have a website and a book that is for sale on Amazon.
Promote them on the web (forums, youtube videos, etc) as well as locally health food stores, yoga clubs, new age shops, conferences, etc.
You can repeat this process with each of those sub niches you see in the PLR products and you can build an entire network of associated "brands"
You also will have every woman in the world hitting on you.
Sincerely,
TheEye
