1. Set an alarm as a reminder to pause and take three deep breaths, whatever you’re doing
2. Bring yourself into the present moment, even briefly, using awareness of sensations in your skin or nose!
3. When you eat, focus on your food.  Don’t do anything except eating, including reading, tweeting, phoning.
4. Check in and “be present” with the breath, while driving; and other sensations such as bumps in the road.  Helps to stop the mind wandering so you arrive at your destination without having noticed the journey.
5. Create morning and evening rituals.  For example, noting at the end of the day one happiest moment, then taking a few deep appreciative breaths.
