What Else?

There are two magic words when someone is sharing their heart, that encourage them to continue. They could be sharing their dreams or baring the big questions in their hearts, describing their fears or recounting past failures.
What else?
It encourages the talker to dare to dream bigger and ask more questions.
It allows the other to have more darkness to share, even when they thought you, the listener, would be scared away.
What else do you think about that?
What else scares you?
What else do you want to do?
What else you got?
This may be the best question you can ask someone.
