Programming Is Reducing Mental Load

The hardest bugs live in your head, not the code.

Great code:
keeps state visible
avoids hidden side effects
limits how much you must remember at once

When you feel tired reading code, that’s signal.
The system is asking too much of your brain.

Good engineering respects human limits.

If it’s hard to think about, it’s hard to maintain.
