Neuroscience is the key to your productivity and now there’s an app for that. No, it’s not a To-Do List, a supportive affirmation or an alarm that reminds you to get back to work. It’s a tool that allows you to uncover when you are most likely to get things done. Peak Time is the long-kept secret of successful entrepreneurs and dynamic over-achievers. It’s your body’s “magic hour”—the time of day when you’re 2-100x times more productive than any other time of day. • Some people call it a “flow state”. I call it awesome. It’s when you can plow through 50 emails in 30 minutes… • Write 2,000 words without batting an eye… • Handle an important sales call while driving through rush-hour traffic with a crying toddler in the back seat… You get the point. And all it takes to reach insane levels of productivity is a few taps of your finger. Yup, you read that right. How it works • Download and open the Peak Time App • Select either right or left hand • When prompted, start tapping the “Start Session” button as quickly as you can • Stop when indicated • Allow the screen to reload to “Start Session” and then start tapping again as quickly as possible, taking care to use the same hand • Stop when indicated • Select the opposite hand—if you chose “Left” first, now choose “Right”, if you chose “Right” first, now chose “Left” • Repeat steps 3 through 6 again. Repeat this process several times throughout the day, for no less than a full week. At the conclusion of the week, look at the statistical map of your results and discover your Peak Time!
