Sometimes you have to force yourself to hit publish, to ship anything (even if the quality is questionable), just to build the habit, just to start moving, just to overcome the demon of not shipping.
Yes, quality over quantity should be your motto and releasing something of real value should be your primary objective, but when you get stuck, the easiest way to get unstuck is to hit publish without much thinking and analyzing.
Don’t worry about quality or perfection too early; worry only and solely about putting your art out there. Once you gain the momentum, once you start shipping at a regular pace, you can concentrate on quality.
Never underestimate the power of frequency and inertia.
