It seems to me that there is a difference between editing and censorship. At least, there is especially a difference between self-editing and self-censorship.
The act of editing is the act of taking away something for the purpose of focus and strengthening. You take something away to make it better. The act of censorship is to take away something for the purpose of hiding something. You take away something not due to qualitative reasons. Truths are hidden. The work is diminished.
So, I wonder, which camp does “He must increase, but I must decrease” belong into?
Is your life being edited, or simply being censored?
Are you growing into maturity to know the difference?
