Good advice is always certain to be ignored
Just do it. I know, it’s an abysmal, mindless cliché of an advertising tagline, but at the same time, it’s simple and it’s true. If you don’t do it, it doesn’t happen. You can talk about writing the book, quitting the job, opening the restaurant or moving to Europe, or you can actually just do it. I only recently figured that out, which is why I have a book. I spent way too much time talking myself out of things, telling myself something was too presumptuous or the odds were against me or I wasn’t good enough or the competition was too tough. You eventually realize that there are the people who storm the castle and then there are the people who sit there and talk about how nice it would be to eventually storm the castle. And if you storm the castle and get an arrow in the eye, at least you tried storming the castle.
