If you struggle to explain something to someone else, there is the opportunity to make it even more clear to you.
There’s an opportunity for both, the listener to see something for the first time and the speaker to see it more clearly by struggling to express it.
Words are clumsy sometimes. Especially when you want to express what’s in your mind, let alone your heart or spirit. But the more you struggle to make it clear for someone else, the more clear it gets for you.
