Very true. Writing success is hard work. I don't 100% agree with the idea, though, that if you write 100 blog posts you will just work it out on your own as a brand new writer. I think writing is like any other skill. We can learn to do it but we also learn faster with feedback from other more experienced people. We can learn to play piano on our own, for example, but learn faster with a piano teacher giving feedback and offering their expert tips. Writers need other writers to bounce ideas off, get feedback from, and learn from. (Which is why you sell a course, right!)
