A person who hesitates is not necessarily lost. They could be chewing on their thoughts, piecing together what's worth remembering.
Pausing does not make a procrastinator, just as disinfluency does not unsettle the words of a writer.
The advantage of doing things slowly is doing them with consistent intent. What remains is important.
We can gather string for years, researching a topic for days on end. But we have nothing to show for it unless we spend the time to piece it all together.
We act, think, edit, curate, and deduce all at the same time, to align reality and imagination to the speed of our pen.
