The Coin Toss.

 If you’re unsure about any life decision — like “Should I read this book or that book next?” or “Should I leave my job or not?” — do a coin toss. Heads you do X, tails you do Y. You are not actually going to live by the coin’s decision, but you need to make a note of your reaction to whatever outcome came of it. Were you upset at what it landed on? Are you secretly relieved? It’s a good way to elicit your true thoughts on a topic.
