Blogging: what to blog about?

HI coaches! I’m feeling stuck because I still don’t know what I’m blogging about. My brain keeps saying, but you don’t have anything to blog about, you’re not an expert at anything. Can you help me with this? It isn’t a good feeling thought but I don’t know how to change it or find a more neutral thought that could help me believe I can actually blog and provide value to people. I honestly, don’t know what kind of value I could blog about.

Thank you!
