In the same that you can project yourself into the future, don't forget to project yourself into the past.
A while ago, I helped my sister using this tool. She was contemplating an important life decision. I asked her if she could remember the "Past Her" that made this decision in the past, she could. I then asked her what "Past Her" would say to "Future Her." She then went on to think about the mistakes she made, available data at the time, and how she would make a different decision in the future.
Back to (the) "Future Her." We explored the scenarios that "Future Her" would be happy, disappointed, or indifferent. We discovered that only walking away from the opportunity would lead to the probability of "Future Her" being happy.
Reflect on the past and project your learnings into the future. You'll see the path ahead of you now - in the present, with more detail and clarity.
Make the introduction, "Future You, meet Past You."
