@jackbutcher put out a brilliant video on this topic yesterday. Here are my key takeaways after the video:
The relationship between these two things is the cornerstone of social capital.
Social capital is the ability to create overlaps.
@david_perell built an audience of people interested in learning how to write.
Audience as an asset-specific to writing.
An asset is a resource that can be built that benefits directly from continuing to grow the audience.
Could create twitter growth products as well.
The writing product that David created overlaps with his audience. As the audience grows, so does the demand for the actual asset.
This creates longevity and ease of scalability.
Created his audience as an asset.
Followed up by selling music, shoes, and even a presidential bid.
As his audience grows so does the overlap of interested buyers for his products. By growing his audience, he grows his business reach.
Audience built by creating free design visuals. Then able to create the design fundamentals course as an asset to sell.
The overlap of the audience's interest and the product means as audience scales that interest in the product does too.
Figure that out by asking questions and measuring reception to different topics. Use Twitter to test.
Social first and then use the social capital to scale.
The best part is that focus on creating value in writing, design, etc. will translate to the ability to monetize as secondary benefit. Do what you love and watch it grow.
