The Optimist's Telescope summary

Every payday, it's easy to get excited about the influx of money in your bank account. You know you should save it for retirement, but wouldn't that new jacket in the shop window make a spectacular addition to your wardrobe? 

It’s the sort of dilemma we face each day: we know the long-term benefits of delaying gratification, but too often we fall into the clutches of immediate temptation.

Imagine yourself in the future at an event you’re looking forward to, like walking down the aisle on your graduation day. If you try, you can probably summon the sights and colors. Maybe you can even hear the din of the crowd and feel the certificate in your palm. Although the event hasn’t happened yet, you are able to conjure all the sensory details of the moment. 

If you’ve ever found yourself daydreaming about a future version of yourself, you were engaging in what cognitive scientists call mental time travel. Your mind repurposes images from your memory to bring a future event to life. And without this ability to imagine the future, human civilization would not exist: there would be no planning, no architecture, no culture. 

Every day, our senses are bombarded with temptations to do what’s better for now, versus tomorrow. When you smell a cookie at the bakery or see a shiny lottery ticket at the supermarket, an overwhelming urge makes it hard to conceive future consequences – even if in the absence of those immediate temptations, you wouldn’t settle for a quick fix. The question is, how can we hone willpower for long-term gains in the face of so much immediate temptation?

Here’s the key message: Planning your reaction to future temptations can help you hone willpower.

Let’s say you want to become fitter, so you set the goal to run half-a-mile a day for a month. Weeks later, your running app dings – hooray, you’ve reached your goal! But when you step on the scale that day, you notice you’ve gained more than a few pounds. You cringe as you remember that you stopped off for ice cream after every other jog – which your running app didn’t measure.

The key message here is: Focusing on short-term metrics obscures the big picture about the future.

When a friend of the author’s decided to run a marathon, she went along to cheer him on. She knew her friend had a festive spirit, so she decided to surprise him at key mile markers by scattering glitter all over him. After completing the race, her friend came to thank her – the glitter had provided him with the boost he needed to endure until the end. 

This is what the author terms the glitter tactic – offering rewards for going the extra mile – and it can go a long way when it comes to thinking ahead.

Maybe you have a treasured family heirloom – a great-grandmother’s wedding ring, or a grandfather’s lucky charm. These items are meaningful because they represent a continuum of history. Passed down from generation to generation, heirlooms turn you into an ancestor with the responsibility of passing it down to your descendants. This is what spurs you to protect your heirloom, so it may outlive you.

The key message here is: The key to foresight is to see yourself – and your actions – as part of a greater history.
