I've been blogging for about 20 years. The first myth to ignore is that you're writing for anyone but yourself. Learn to enjoy the process of telling your story, of capturing your ideas, of explaining what you learn. Few blog posts are read by anyone but the author so you'd better get pleasure and satisfaction and use from blogging. The act of blogging has intrinsic rewards, from improving your writing skills to boosting your memory. With time, readers may come. But start bare bones and share your journey of discovery with your future self.
