There are many amazing tales of writers who suffered a lot from poverty and then with writing earned fame and fortune. In the recent past, the best example perhaps is J. K. Rowling. She was suffering a lot from money problem and loneliness when she was writing Harry Potter. Of course, she is skilled and talented or else so many people would not buy her books. However, she is some lucky too.
Anyway, what I want to say is that when you decide to become a writer then first of all, look at your purse. If you do not have enough money to pay your bills then don’t become a full time freelance writer.
