How many people are you actually competing with?

2 years ago I wrote about an idea that's changed how I think about careers and startups.

We often compare ourselves to millions of people, but in reality we're usually competing with a much smaller group. The post breaks down why that is, how it affects motivation, and what it means for choosing what to work on.

Curious whether others here agree or think this reasoning is flawed.

By the way, I ended up passing the Investment Committee at Entrepreneurs First and raised $250k for pre-seed, which completely changed my life. After that I moved to San Francisco and tried to raise a seed round but failed :)
