Eavesdropping at work

Lately, circumstances have dictated my need to work in the actual office instead of from my home.  When in the office, I typically play music through headphones and drown out distractions.  Today, I had not yet put the headphones on my ears and heard someone say, "If you don't look out for yourself, no one else will."  How many times have I said that!  Hearing that made me ashamed.  I'm not, nor should I be, first.  Christ should be first.  Showing His love should be my priority.  I am so guilty of forgetting that.  What a reminder today.
