If you could go back to the beginning and start again, what is the one thing you would change? You might be able to think of several, but there’s only one that really matters—and it’s the one you haven’t noticed. In the next few weeks, it will appear clearly, and you’ll be amazed that you missed it. Here is your chance at a fresh start. Tell yourself that this time there will be no mistakes.
