  3. Hire for low ego, title-blindness, and a willingness to pitch in, because the best hires often don’t match every line on the job spec. Be prepared to sift through candidates and make the most of the skills you find.

🕹 Technology Quality Assurance Software Reliability Testing Systems Data
  1. Even careful, human-made reference works often contain hidden errors that get copied forward. Cross-checking helps but won't catch everything.
  2. Modern computing faces the same problem at much larger scale: chips and software can produce subtle wrong answers, and huge datasets often make full verification impossible.
  3. The right response is to design for detection and tolerance by using redundancy, consistency tests, and processes that reduce mistakes. Practices like pair programming and business-facing code review help you "trust but verify" and make systems more resilient.

  2. Five common patterns stop people from achieving macro focus — unclear goals, juggling too many priorities, not doing enough, doubting the plan, and quitting too soon — and each has a clear fix like getting specific, picking one primary focus, scaling effort, trusting a documented plan, and setting realistic timelines.
  3. Macro focus is a skill you can build by defining what success looks like, making concrete weekly commitments, using checkpoints and external support, and then sticking with the plan long enough for results to compound.
