My best thinking is when I am going for very long runs, when I write down the thought, my brain stops thinking about it, considers it done and moves on.

When writing, thoughts become forced and linear in my view as opposed to floating in a specific way from point to point. Like I lose the natural creativity.

Writing is about remembering or communicating, so it is summarizing the thoughts, but it is not thinking itself, it is more so thinking about how to communicate efficiently or how to make a note so you don't forget. It is not creativity for me.

Kind of imagine building an idea in your head while running and then you write down the summary of it.
