I see two paths towards a more earnest culture:
1) Glorify the revision process. The goal would be to illuminate the messy middle steps that underly successful endeavors. For example, in his interview with Ben Casnocha, Colin Marshall suggested a museum of rough drafts that would emphasize how most everyone’s first draft sucks. This applies particularly well to art but generalizes, as we could include first business plans, first lines of code, and first experimental designs. If these messy middle steps are glorified then people will be more willing to share them.
2) Shun those who act mysteriously. Mysteriousness is cool because it emphasizes the short run over the long run. In the short run your onlookers will think of your success as effortless, which will raise your status. But in the long run, nobody knows how to help you or whether they can offer you advice, because you haven’t made your plans transparent. So we should punish mysteriousness and unabashedly pressure people to open up.
I love the idea of a Museum of Rough Drafts.
