Being discreet is important but talking is our way of expressing what we want or believe.
Often we talk with our body and in doing that we speak louder than our voices could ever say. Try listening to the other person with your eyes. Look deeply back into their eyes and you may get a glimpse into their soul. Staying in tune with your senses will be a new way of listening and might also give you the opportunity to stop talking too much.
With practice you may improve your connections with another soul and eventually words can be spoken silently with your eyes even across a crowded room.
In our world today we have so many distractions that we forget how much power we have to communicate what we want or believe by our actions as well as our words.
