Firstly define how do you want to feel or enforce somebody to feel with settled anchor. If you talk to a friend who is nervous, anxious, you just propose him to remind or imagine something very pleasant he had in past (go back to the nice and calm experience, but strong emotionally). Just close eyes and imagine. When he is in process of reminding you might probably see a slight smile on his face.

To create an anchor you have to touch him very specially somewhere in unusual place (may be press by finger his arm or shoulder). Anchor means that next time when you’ll press his shoulder in a same way he mush automatically remind his mind state of last time when you’ve settled anchor (a pleasant state).

You can apply anchors to your own mind as well, having a exciting potential to fell yourself in a way you want (or need) to feel.
Relax, go back to your memory, find strong exciting feelings in a past. Now try to feel them again in a full and when you’ll reach a peak of this emotions make an unusual gesture or touch yourself in special place.

If you made an anchor properly it will enforce you feel excited when you need it to resume this state. Of course it requires a practice, but it worth to master.
