There are thousands of tips. Here are a few:
- Don’t expect to earn your living as a writer because it’s very hard but, as an avocation, it’s great. If you truly want to make your living writing, then spend a whole lot of time finding out what kinds of writing pays and how to do that writing. (Because it is possible to make a living as a writer, it’s just not the norm.)
- Read, read, read because that’s how you’ll find out what other writers have done successfully. Then copy those writers.
- Write, write, write and don’t worry about quality. Just do it and eventually, the quality will come.
- Take classes, read books, go to workshops and conventions and listen to what experts say. Follow all that advice.
