Anchoring can be a physical action, an image, a sound (word), or whatever else works for you. The key is to reinforce the anchor a number of times when you know you're in the desired state. Make sure that whatever you use as an anchor is a unique action, sound... that you can easily replicate. It's common to make it a discrete event so that you can do it in public if you need to. You can also combine anchors (e.g., a word plus a physical action). Does this help?
