Every day, there are a handful of moments that deliver an outsized impact.I refer to these little choices as decisive moments.The moment you decide between ordering takeout or cooking dinner.The moment you choose between driving your car or riding your bike.The moment you decide between starting your homework or grabbing the video game controller.These choices are a fork in the road.Decisive moments set the options available to your future self.For instance, walking into a restaurant is a decisive moment because it determines what you'll be eating for lunch.Technically, you are in control of what you order, but in a larger sense, you can only order an item if it is on the menu.If you walk into a steakhouse, you can get a sirloin or a rib eye, but not sushi.Your options are constrained by what's available.They are shaped by the first choice.We are limited by where our habits lead us.This is why mastering the decisive moments throughout your day is so important.Each day is made up of many moments, but it is really a few habitual choices that determine the path you take.These little choices stack up, each one setting the trajectory for how you spend the next chunk of time.Habits are the entry point, not the end point.They are the cab, not the gym.
