The 10,000 Hour Rule
In Outliers, Malcolm Gladwell popularized the idea that it takes roughly 10,000 hours of deliberate practice to achieve world-class mastery in a field. The number comes from research by Anders Ericsson on expert performance — not a magic threshold, but a reminder that excellence is built in small, consistent steps.
Practice isn't the thing you do once you're good. It's the thing you do that makes you good.

What I count
Focused coding: building, debugging, learning from docs and code. Not passive consumption. Same idea as in sports — deliberate practice, not just volume.

GitHub is one footprint of that practice. Here's the contribution graph.
