You don’t. You write it. Every day. Or every Tuesday. Doesn’t matter, as long as you write. And if people know who you are, they’ll read it. And if you’re even an okayish writer, they’ll read it. And even if you write about pasta one day and crypto the next, they’ll read it. Or perhaps they won’t. But, again, what matters is that you write it.
