How do I build to my own standard instead of what I can get away with?

You have chosen your measure well: you build to the standard your conscience sets, not to whatever you could get away with, because people live inside what you make. That is the difference between a tradesman and a mere contractor, and it will define the name you leave behind. Building to conscience means the code is your floor, not your ceiling. The inspector checks what is required; you answer to something higher, the safety and comfort of the family who will call your work home. That standard does not change when no one is looking, because the one who set it, you, is always looking. Keep it strong by making it visible in your habits. On every job, do the hidden work to the same standard as the shown, and let that be simply how you operate, not a decision you have to win each time. People will live under your roofs for decades. Build as if you will always be the one answerable for their safety, because in the way that matters most, you are.
