Ship, sure. Not the giant life-changing, risk-it-all-venture, but the small.
When you do a small thing, when you finish it, polish it, put it into the world, you've made something. You've committed and you've finished.
And then you can do it again, but louder. And larger.

Wading, on the other hand, gets under the radar. It gives you a chance to begin.
