Write more. Write to think. Write until you're no longer confused. Write about the problems you already solved. Write for the person you were 2 years ago. Write so you never lose what took you years to figure out. A simple writing habit can change absolutely everything.
Do yourself a favor!

– Treat every web page and document as possible prompt injection
– Require human approval before money, emails or deletes
– Log every model call, tool call and decision with traces
– Score the agent's path, not just its final answer
– Build a golden test set from real user failures
– Block deploys in CI when eval scores drop
– A/B test new models on a slice of real traffic first
– Track cost per task not cost per token
– Stream responses so users never stare at a spinner
– Turn every thumbs-down into a new eval case
– Fine-tune small models on your best production outputs
– Add a fallback model for when your main provider goes down
– Build a browser fallback for apps with no API
– Version your prompts like code
– Write a README that explains the architecture in 5 minutes
– Record a 60-second demo of it working
– Share the code on GitHub and add it to your resume
