Listening.
To hear something with thoughtful attention.Good listeners are rare. They are always in demand at social gatherings. Good listeners bring their full attention to the speaker. No butting in, no thinking of what your reply will be, just open, honest listening. When the speaker is finished there will be time to formulate your reply. Patience is the key, understanding the lock it opens. All our lives we learn from others, and the more we learn the more we grow. This is serious business -- listening -- become an expert at it. You will be in great demand, as well as gaining wisdom in the process.
"Knowledge speaks, but wisdom listens."
Jimi Hendrix
American rock guitarist, singer, and composer, 1942-1970
