Here’s what I said:
Creativity comes from ruthlessness.
Being thoroughly ruthless with what you have and what has been done will allow you to create something new. If there is something that is equal to your abilities, i.e. you do not have command of it, then that thing is something new, at least for you.
If you are unwilling to be ruthless then you will know that the work you are doing does not require your full attention and you will be selling yourself and your creativity short.
