You don't know what you have to say until you say it.
What do you believe?
Well, you have to sit with the problem. You have to work with it. Examine it. You don't know what you believe until you write.
And then once you share it with someone, you'll say again, “Do I really believe that?”
Then you'll be back to the drawing board, and this will be good because you'll be further from vague and abstract and closer to truth.
