Here is another quick resource for practicing midnfulness. It's called "dropping anchor." This can be done anywhere, at any time, in nearly any circumstance. It is a simple exercise to center yourself and connect with the world around you. Practice it throughout the day, especially any time you find yourself getting caught up in your thoughts and feelings.
Plant your feet into the floor.
Push them down – notice the floor beneath you, supporting you.
Notice the muscle tension in your legs as you push your feet down.
Notice your entire body – and the feeling of gravity flowing down through your head, spine, and legs into your feet.
Now look around and notice what you can see and hear around you. Notice where you are and what you’re doing.
