Tip No. 1:
Try what teacher Pema Chödrön calls "pause practice."
Stop whatever you're doing and take three mindful breaths.
Or just focus on the sounds around you for a few moments.
That's it. Done!
Tip No. 2:
Practice mindfulness of your body anytime: notice the feel of food on your lips when you eat, the ground under your feet when you walk, or the phone in your hand right now!
Set a mindfulness reminder on your phone or install an add-on or extension to your browser.
