Tone is incredibly important in music. Bad tone, bad music. In leadership, tone is also incredibly important. Tone of your conversation, tone of a meeting, tone of your reprimands, tone of your encouragement, tone of confrontation, etc.
Let's be clear- I stink at this. And lots of us who are intense Type A's need to work on this. The ENTJ in me many times doesn't care or even think about what my tone might be saying or in some way impacting those around me. Too many times I am completely tone deaf.
So think about your tone. Be it in what you say, how you say it, what your posture is when you say it, or even the way you don't say something.
It is saying much much more than we might think. Just ask those around you.
