I started with stories and several aborted novels, then moved on to poetry from about age 25 to 45. Reams of rubbish with a few gems. I started a novel to deal with my divorce, sparked by reading Schismatrix, in early 2017. I had no intention to publish it, but I showed it to a novelist friend who showed it to his editor and she published it in 2019. I'd be lying if I said I wasn't totally stoked, but I used to write more out of compulsion than anything else. I made my first attempts at 17 but it wasn't til 21 or so that I really got into it. I occasionally sent stuff out, and of course would love to publish again, but I do it because I kind of have to. Fame or money, I wouldn't turn it away, but it's really not why I do it. I think to become a writer one must read constantly and write every day. Innate talent ain't anything without practice. Thing for me is since being published, I've slacked off on both reading and writing. It's easy to lose the habit. It's kind of a snowball effect, when I write I write and write and write. For about 9 months I haven't written jack. But I'm not gonna force it. When it comes, I must write it out. At the moment, I just don't feel the compulsion. It just seems fake. I was a machine for over 20 years, so I think I need to just absorb and reflect. Not sure if that's helpful. My advice: read incessantly, write daily, don't try to say what you don't know or be who you aren't. And don't be afraid to experiment: I've used cut-up, found text, automatic writing, just for me, not for public consumption. The book I published is "poetic" and maybe even "lyrical" but it's relatively straight. Buk's "Don't Try" is a good bit of advice. Or as Yoda said: "There is no try. Only doing". Also, sometimes people will write a certain way because a literary hero, say Bukowski, approve or disapprove of a certain way of writing. This can really cripple a writer. I learned a lot from Bukowski and wrote quite a few poems with his voice in mind, but ultimately you can't stay locked into that. It's not wrong to imitate another writer but eventually that's just got to be a phase on the way to discovering your own voice, which will reveal itself after many years of work. You'll look back and see where your influences fell away and "you" began. I hope that helps an doesn't sound pretentious.
As an afterthought, I have to work a job, but not having a lot of time is actually beneficial to me. I tend to do less when I have a lot of time. "I'd only write if I only had time" is rubbish. Whether it's five minutes a day or five hours, you take that time and do it. Precious few make a living by writing, so you just have to make that time you have count. I compose lines in my head while driving, or jot stuff down between classes or whenever. No excuses, basically. All you need is pen and paper and minutes wherever you can find them. I hesitated to post this link, but it does speak a bit about how I write, it's an interview I did for my publisher, it goes into some details about what I've said above:

I hope that's useful.
