Why don't you consider packaging up your knowledge and make money via digital products?
For example:
- This guy turned his Google Sheets tutorials into a $200k business
- Writing a book on web application deployment and making $40,000
- Making $2,500 monthly Roasting People’s Websites & Products
I run this site where I interview indie founders on how they started and grew their business and side hustles.
Hope you find something there for yourself. All the best!
