Part of being passionate about something is being dedicated enough, diligent enough and determined enough to research it on your own. If you don't have the passion required to summon the dedication, diligence, and determination required to make your dream a reality, then you're obviously not anywhere near as passionate as you'd like to think you are.
Being passionate about something doesn't mean that you're qualified to actually do it. There are plenty of people who are passionate about music, sports, writing, all sorts of different things, who just don't have the level of talent required to stand out in any of those fields. 99.999% of the writers in this world don't make enough to live off of selling their writing. Possibly 1% of 1% of the writers on this planet achieve some degree of wealth or fame, and the percentage that achieves some type of meaningful acclaim is even smaller.
Writing isn't about changing lives. Footballers and pop stars don't change lives either. That's just a silly myth that amateur writers like to believe because it's easy to be idealistic when you're wholly ignorant of the way things work. Writing for profit is about producing something that sells enough to make money for everybody involved - authors and agents and publishers and vendors alike. If an author doesn't have an agent or a publisher, then he or she will have to assume those roles. There are simply way too many variations on the writing process and the publishing process and the marketing process for anyone to outline each of them for you here. If you really and truly want to write and you want to earn a livable wage from doing it, you'll have to commit the time and effort and energy to figuring out your own path to putting yourself into a position where you might make that happen.
A couple of other things that you might not be aware of: Writing is a job. Just like anything else that people do for money, it's work. It's not carrying pianos up and down 6 flights of stairs, it's not breaking rocks, it can't be compared to doing manual labour or working in retail, but it's still work. And if you choose to be a writer, it will be a job and you'll have tasks that you'll need to complete and benchmarks that you'll need to hit just like everybody else does.
Lastly, it makes very little sense to attempt to peddle your writing in a foreign language. English is not your mother tongue. Why would you present yourself with the obstacle of attempting to flog your writing when it's not going to be up to the standards of native speakers? My favourite author of all time wrote in French, but my French is awful. Why would I attempt to compose in French? There are already millions of writers who write in French, they're fluent, they can wield the language in a way that I would not be capable of doing, probably forever, but definitely for the next few years at least. Why not write in French? If your writing is any good, it will find a market with readers who are fluent in French, and if it's deemed worthy of translation, it will be made available to speakers of other languages.
Music and sports are universal. Anyone who aspires to football or rock music doesn't need to worry about language, but if you want to write, it's incredibly important. Nobody is going to pay you for snippets of writing that sound as though they were cobbled together by someone with a tenuous grasp of English.
- Research different options including many different types of writing, you may have to begin by doing something that doesn't particularly interest you such as advertising or copy-writing, etc.
- Work towards accruing whatever requirements most paid writers possess, a degree, some experience, references, writing samples, etc.
- Accept the fact that life doesn't fall into line because you happen to have a dream, you won't be getting paid "right now" as you aren't capable of producing anything worth paying for at this time.
- Come to terms with the fact that the realisation of your dream is going to be a process, not something that will happen at the flick of a switch. Patience is a virtue in all forms of writing, work to develop some, along with the dedication, diligence and determination that I mentioned at the very start.
