Retrograde Analysis

It means looking backward to solve problems. Instead of starting from the beginning, start from the end.

Example:

• Imagine bacteria doubling every day. If a lake is full after 60 days, when was it half-full? Many will say day 30, but the answer is actually day 59. If you think backward, it’s much easier!
• If you’re planning a trip, start with your return date. What do you need to do before that? Book your accommodations first, then plan your activities around that. This way, you’ll have a clearer vision of your itinerary.
