What does it mean that trigger placement in your environment?

Position trigger cues where you will encounter them at the right moment.

Example: You want to read every evening. Leaving a book on your bed pillow means you physically cannot go to sleep without moving it — the placement forces a decision point. Leaving the same book on a shelf across the room means you have to remember, get up, and retrieve it. Same book, same intention, same motivation. The only variable is placement. One version works. The other requires willpower you won't consistently have.

Try this: Choose one behavior you want to trigger more reliably. Identify the exact physical or digital location where you'll be at the moment you want the behavior to fire. Place a cue there — a physical object, a sticky note, a tool positioned for immediate use. The cue must be impossible to miss and require zero retrieval effort. Test it for three days and note each time it fires versus each time you walked past it.
