Take 5 mins out of your day to sit down, straight back, close your eyes, take 3 deep breaths and settle into a meditation. As your mind chatters just gently bring your attention back to watching the breath rise and fall. No need to manipulate it, just watch its patterns as it comes and goes. Keep returning your focus to the breath. See how you get on and keep coming back to the practice every day. Repeating 5 mins a day is better than sitting for one, half hour session, get the consistency going and watch the benefits.
