Oh, hey, people remember me!
Well, first off: what exactly do it means to the author to succeed? Having a good writting? Being famous? Getting enough money to survive?
The first one is easy: you get good at things by studying them and doing them. So go read books about writting, maybe get yourself iinto a creative writting course on a college or university or even a online one, there's plently of them. An write a lot, without fear of being shitty at it for a while. You will get better.
Getting famous is harder, but depending on how much famous you put the line to be a success, it's achievable. Mostly, get your work out there, and you eventually you will hit the finish line. I have seen people doing podcasts and youtube videos as a side to their writting, especially because it can get you some ad money on the side as well. Which is nice because...
...the last and most hard of them is getting to live on writting. Not gonna lie, that was my dream for the longest time in my adult life. From 18 to about 29 I believed that I could break the clouds and have my place in the sun as a writter. Then I finally made the math and noticed that even being a sucessful writter in Brazil means you're living barelly above minimum wage. I mean, a guy who seels 3 thousand copies of a R$40 novel in six months is a beast, a nascent superstar in the book market. He also got to live with about R$ 2.000 a month, which is a little more than a intern at a bank makes on average. Except that the book could have take him more than six months to make, and then more than that to get from first draft to final draft to publishing. If it took a year, then he's making about R$ 1.000 a month, which is R$ 2 more than the minimum wage in Brazil. It's also R$ 200 less than the average wage of garbage collectors. And since writters don't work on the CLT (the worker protection laws of Brazil), they don't get vacations, sick days, food and transport tickets, 13th salaries (in Brazil, by law, in december you get paid two salaries instead of one), so at the end of the day the up and coming writter that is selling 50% more than the average print run of most books in Brazil (which is 2k)? He's living below the poverty line.
And that is the sucessful guy, most books are sucessful for the publishing company if they sell 50% of their print run in six months, with a average print run of two thousand books, and a price tag of R$ 40, along with the standard 10% of the base price tag as royalties, that means R$ 4.000 in six months, or about R$ 666,66 per month, about two thirds of the minimum wage, but then there's the problems we already talk about so suddenly a average writter in Brazil makes about R$ 300, and the poverty line in Brazil is at R$ 387 of monthly income.
This, of course, is if nothing bad happens. For example, in the last 12 months, the company which published 2 of my books didn't pay my royalties. Its not from a lack of money, since they had a sucessful crowd funding campaign for a new book that got them R$ 1,918 million. In said campaign they also sold 44 copies of my books as part of the add-ons for the pledges. They just think they can get away with not paying, and they can, because what writter living on barelly a minimum wage can afford fucking litigation costs?
So, there's that. I don't know how you can get yourself living confortably as a writter. I don't think it can be done in my country at least. Sure, if you hit it big as an actual superstar that sells tens of thousands of books per year, then sure, but there must be like 20 guys tops country wide who can do that, if not less.
