Great reminder. I remember talking on the phone with one of my employees. It was a day off and my family and I were driving somewhere. My employee called me to give me an update on a bunch of things that were happening and at the end of the call, I said "good job". I hung up the phone and my wife turned to me and said - that wasn't good enough, you need to tell your employee what they specifically did that was good. High fives, thumbs up, and "good job" can go so much farther when you add something specific to it... like "Good job on that phone call, I like how you said X".
