Don't agree. I think that is like saying you can become a professional athlete by just working out everyday. We mostly know what works. It's comradely, career and cash. Most things worth doing isn't going to result in much professional progress or money in the beginning, so working with and showing things for your community is generally the most important. That's what driving every sports team, music group, enthusiast etc. in the beginning. You still of course need the time, knowledge and motivation to do something.

Shipping can be the result of, or one way, to do the right things. But if you look at projects on Github it's usually not a lack of "shipping daily" so much as a lack of packaging it as something useful. Often you see daily commits until the motivation wears off and the project stops. But the software is still buggy, there's no screenshots, it's not straight forward how to build it, lacks documentation etc. They haven't made it into something that is easy for other people to appreciate, so they don't get much positive feedback.
