Attention is more valuable than time. Which do you prefer? Thirty minutes of time with someone and five minutes of his or her attention, or ten minutes of time with someone and all ten minutes of his or her attention.
The competition for the attention of others is fierce. If you fail to win, then you become "background noise," much like the music in a hotel lobby or a coffee shop. We all know it is there, yet seldom do we actually remember the drone. Our capacity for attention is limited.
Learn to manage your own attention when communicating with others. Pay attention to them before asking for their valuable attention. You've probably heard that "time is money." However, when communicating with others, attention is gold.
