A very helpful practice to stay present in my life is establishing Touch Points in the body.
I have chosen three places in my body where I can strongly focus my attention: my neck & shoulders, my heart, and my lower abdomen. Several times during the day I stop and gently breathe into these Touch Points, relaxing them and feeling them fully. It has become a nice habit to pause and connect with my body in this way.
The good thing about establishing Touch Points when life flows on normally, is that when I find myself in stressful situations I (hopefully!) remember them. Then I connect with my body, calm down and come a little bit closer to being in peace again...
