We measure by wstimation in lots of everyday
things, too. In the morning, you estimate how much
orange juice you want for breakfast by pouring it into a glass. It's not a precise amount, just approximate. And you measure by estimation when you cross a street well before a car comes or when you pass a football to a running teammate.
One thing most of us don't measure often enough, though, is ourselves. How often do we stop and say, am I doing the right thing? Is it what a Scout should do? How am I measuring up the to the Scout Oath and Law?"
I suggest that you set aside 5 minutes a week to pause and ask yourself, "How am I measuring up?"
