I've always wanted to write and illustrate kids books so that's an option too.
I just saw this
the covers I'm talking about in my post are definitely not children's books unfortunately!
The problem with books and publishing if you are someone who has "always wanted to write" is that there are two routes to financial success, and if you remove the people at the very top of the traditional pub route who skew things massively, the vast majority of joe-bloggs people who are making a decent living of $40+ are indie or at least started that way.
And the problems with that are: some genres / markets are just not for indie authors. Many try, few make money, most give up and never quit their day job. Children's books is one of them.
Which means you have to write in genres where readers don't notice you are indie, or are fine with it, or actively looking for it, or completely underserved and forgotten about by traditional pub.
This limits you to genre fiction like SF&F, Romance, LitRPG, Male Fantasy (romance for him), and Cozy/Mystery.
Thrillers & YA, harder but not impossible.
Memoir, Literary, Children's, Mash Up of Whatever I, The Author, Felt Like Writing... keep the day job and buy lottery tickets.
And thus we have to change from "I always wanted to write X" to "I write for money, I write exactly what the market wants. I write fast, so fast people probably won't believe me and if they do they will assume it's utter shit. (They will also tell you that, regularly). I write one draft and mandatory rewriting, 2nd drafts, letting it stew for a year etc are myths. I write in a style that is easily digestible and addictive because I am literally getting paid half a cent for every page a reader reads and I want them turning those electronic pages."
It is not romantic. It's not sitting around waiting for inspiration to strike. It's hard, people will hate you, readers will assassinate you, other authors will tell you that you're doing it all wrong (particularly if they're not making as much money as you) and you will write a metric shit tonne of words.
But if someone can get past all that, commit to learning and getting the work done, and can do it well... then it's absolutely the best job in the world. I genuinely love it. Every time I get a gushy message about a fictional person I invented I go all warm inside. The fact I make money from nothing more than my thoughts is mind-blowing and I have to pinch myself daily.
It is definitely a creative career that pays very well, but you have to be very deliberate about making that happen.
