For those new to mindfulness I would highly recommend reading ‘Mindfulness: A Practical Guide to Finding Peace in a Frantic World’ by Mark Williams and Danny Penman. Mark Williams is a Professor of Clinical Psychology at Oxford University.
Before you rush out to get the book I would recommend beginning by listening to his recordings once or twice a day before bed and/ or in the morning or if you have spare time during the day. I would recommend listening to the same recording more than once to the point you feel you can understand and practice his directions before moving onto the next.
Hope this helps and remember you can miss a day, week, month or year and always return to practice when you are ready.
