Here’s how to do it:
Step 1: Write down what you did today and how you felt about it—who you talked to and a summary of your conversation—what you noticed and learned.
Step 2: Do it again tomorrow. And the next day. And the next.
Step 3: Once you’ve been doing it long enough, wrap up each session by reading what you wrote exactly one week ago, one month ago, and eventually you can go back even further.
Two things happen when you time travel:
First, you will become amazed at how unreliable your memory is. We remember wrongly, and we forget things quickly.
Second, reading what you’ve learned in the past, you’ll be a lot less likely to make the same mistakes over and over again.
The goal is not to be perfect, but to make new mistakes rather than old.
