Answer by A Quora admin:
When I was in high school, someone once made a joke saying
If you want to make money, write a book about making money and sell it!
That was before the internet became affordable to everyone. Now, you could write a book titled "21 sure ways to make money" and express your opinions about each. Research properly and gather testimonies from people who have tried and succeeded at those attempts.
Okay? Or you could find something you're passionate about, and start blogging about it. Build an audience, build traffic, then start selling small adds on your blog. It's not making more from writing directly, but your writing attracts the traffic, which makes advertising valuable on your blog.
Or you can considerwhich I came across recently. If you're an expert in a field, you can sign up to write for them in that field and you get paid.
You can give tutorials about something you're good about (in a book, in a blog, etc.) and I'm sure there are lots of people who would pay a token to learn from you. Remember, you don't have to be a "guru" at something in other to teach others, you just need to be better than them.
I hope this helps
