My husband is a college professor and he is forever telling his students that real life is going to come at them hard and fast. That when they turn in late assignments, miss class or fumble around on a group project that in real life, those kind of mistakes could keep them from getting a job or even get them fired from a job they did land.
After being in the business sector for over 20 years then switching over to teaching college classes, he brings a ton of 'real life' experience to his students who eat up everything he teaches because it's the real deal. They know what he tells them works or won't work because he's actually done what he is teaching. When they mess up he endearingly reminds them that "it's a life lesson, learn the lesson, pay attention to your life!"
We could all use a shot of 'paying attention' to our lives. We get up and go every day, doing much of the same thing we do every day, but do we stop and realize this is my life? I need to pay attention to it because I don't get another one. As Christians, we realize after this life, whether we get to Heaven or not depends on what we are doing right here, right now!
So learn your lessons, pay attention to your life, right now!
