You may be less likely to take initiatives or take risks. Many of your experiences will be very enjoyable without much effort on your part. There's no situation so bad that you can't make worse by how you think about it. Riling against unwanted events can worsen their consequences. Your objections can create struggles, interfere with your learning, consume your vitality, create adversaries, and block you from moving on with your life to engage more pleasant events.
People rush to judgment when they think events are bad.
For example, people ensnarled in traffic on their way to JFK were probably frustrated and angry when they missed their flight. They whined and complained until they learned about the catastrophe on their scheduled flight, EgyptAir 990. This new evidence may have prompted their gratitude for the life-saving benefits of traffic jams. Traffic snarls may have saved the lives of your loved ones many times. Rarely does the world provide immediate evidence about the benefits of unwanted events.
