I’d like to share this photograph of Earth from Saturn’s orbit, taken by the Cassini probe in 2013.
Earth is that tiny point to the right & down from the center.
Carl Sagan’s “Pale Blue Dot”, a reflection on a photo of Earth taken by Voyager 1 in 1990, comes to mind:

The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. ⬇️
It has been said that astronomy is a humbling and character-building experience. ⬇️
Maybe it is exactly this which will change our minds as a collective race - to have a deep awareness of how insignificant, fragile and isolated we are in the vast cosmic emptiness of space.

Like company moats, your personal moat should be a competitive advantage that is not only durable—it should also compound over time.

I'm increasingly interested in the idea of "personal moats" in the context of careers.

Moats should be:
- Hard to learn and hard to do (but perhaps easier for you)

2/ Like a company moat, you want to build career capital while you sleep.
As Andrew Chen noted:
People talk about \u201cpassive income\u201d a lot but not about \u201cpassive social capital\u201d or \u201cpassive networking\u201d or \u201cpassive knowledge gaining\u201d but that\u2019s what you can architect if you have a thing and it grows over time without intensive constant effort to sustain it

3/ You don’t want to build a competitive advantage that is fleeting or that will get commoditized

- Proprietary networks
- Being something other than one of the best at any tournament style-game

4/ Before the arrival of recorded music, what used to be scarce was the actual music itself — required an in-person artist.
After recorded music, the music itself became abundant and what became scarce was curation, distribution, and self space.
5/ Similarly, in careers, what used to be (more) scarce were things like ideas, money, and exclusive relationships.
In the internet economy, what has become scarce are things like specific knowledge, rare & valuable skills, and great reputations.
