Daily is easier
There is a maxim in the software industry that says "if it hurts do it more often".
Publishing something I wrote is hard. Publishing every day is easier.
Writing and publishing a piece is hard when that piece is the one "perfect" piece I will be publishing. Writing and publishing is easier when there will be another one tomorrow.
With the one perfect piece, I have a high expectation that everyone should read it. With the daily piece, I just want to have one idea - published daily.
