The key to feeling these exercises is consistency. Commit to do this everyday for a few weeks and before you know it, its part of your routine and not a task to be "accomplished" as part of our to-do list. Once the brain is trained it will look for more opportunities to take a "breath". If it doesn't come natural or seems forced, just recognize that it is nothing, laugh at your minds stubbornness and agree today is not working, it is not a failure but is what it is without judgment. Tomorrow is a new day.
