"Go where the money is."- well-said, there are a lot of trivial jobs offering money as long as you know how to copy and paste. I once did that kind of work a lot, but I found out that the amount of money didn't worth the time of sharpening my writing skills.
I think that writing to have fun and writing and making money can coexist together. Once your blog or platform takes off, you'll have a greater possibility of selling classes and selling subs.
Although my parents always tell me not to do things for a purpose, I think I need to do the right things and stick to them and make them become my habits, and I can end up realizing the purpose without even noticing.
