I wanted to pause here to clear a few things up.
Everyone makes mistakes and always will. We aren't perfect. What we can do is make fewer mistakes. We can improve. There's plenty of reason for optimism.
You don't need to be a genius to understand any of this. If you make an effort to understand and try to pay attention to what you're reading without making assumptions, then you should be OK. If you've understood so far, there's no reason you can't understand the rest too.
If you do challenge yourself to understand, but it's not working, that's probably my fault. Maybe I wrote something badly, made it overly complicated, or left something important out. Sorry!
Or maybe it's no one's fault. Communicating ideas is pretty hard. Miscommunication and mistakes are commonplace. Regardless, there's a solution. Email me and I'll do my best to answer your questions or improve the site.
