It doesn’t mean you should ship subpar work. On the contrary, it is the opposite:
Ship the best work you can do that day.
Write a song once per month and you have an album by the end of the year.

Produce one water color picture per day and that’s enough to make a living.
Shipping is the key.
Progress over perfection.
