I think that all hundred courses are ridiculous because like they're giving very generic advice to a lot of people. I have given my LinkedIn playbook to my friends for free who tell me they want to get really good at LinkedIn and I can track how many of them have actually used it. So when you're writing with an outcome in mind it always brings you back to your audience. You start sharing things that are specifically helpful and help your audience solve a very specific problem. If you know your outcome if you study copywriting if you can get people to stop their scroll the last thing people are going to do is go look at who you are.
