I hope it helped. It's a 3 minute mindfulness "arriving" exercise we did on my MBSR course. I rely on it so much. It doesn't take long and the more you practise it and you give yourself permission for those few minutes it gets easier and you are able to be less distracted and more focussed. If you are distracted, that's ok, just bring your thoughts back to your breathing. There is no harsh judgement or "failing" on this.
