Productivity Principles

  1. Batch similar tasks — Write all summaries at once, not one-by-one
  2. Use Claude for thinking, ChatGPT for doing — Claude for strategy, ChatGPT for quick execution
  3. Automate the repetitive — If you do it twice, automate it
  4. Don’t optimize tools, optimize workflows — The best tool is useless if it doesn’t fit your process
  5. Free tiers first — Try before buying
