I mean, why not? I’ve started plenty of projects that went nowhere, because I wanted to.
Starting a blog has multiple ways to start, there’s like Substack, Blogger, but I haven’t used them. Or you can make a website if you want all the creative freedom for the feel and look of the blog—that just costs a monthly fee so maybe start with the aforementioned sites. A way to gain more traction from 0 would be creating social media posts out of your blog posts, and outfits. That way people will see you well before the website.
I do work in marketing so if you want to talk I'm free for a couple hours, or later tonight.
Enjoy the journey, you got this!
