The 90/90 rule is simply for the next 90 days, spend the first 90 minutes of your work day on your single most game changing opportunity. Because what happens? A lot of us get to work and we spend our best hours on our least important activities. We get to work and we start checking our social feed. We get to work and we just check our texts. We get to work and we chit chat at the water cooler about the latestTV show that we watched last night. And research has shown that the morning hours are when you have the most focus, when you have the most energy, and when you have the most willpower. And so you want to use that first 90 minutes, that is game time. That’s show time.
