Friendship is such an important part of our lives but how much do we really know about it? Do we understand how it works, what it is and what it means? In her last book, Caroline Millington introduced us to the concept of kindfulness - blending mindfulness with being kind to yourself. Simply, remembering to treat yourself with kindness in all instances. That means setting boundaries to get the best out of your relationships and making your emotional wellbeing a priority. The Friendship Formula shows readers how to apply this concept to create and maintain longlasting, nurturing and functioning friendships. Friendship is a beautiful thing but there are lots of difficult times in life where it can be tricky to navigate: when friendship becomes toxic; how to break up with a friend; what to do if a friend 'ghosts' you and surviving friendship betrayal; how motherhood can impact on female friendships; friendship grief and how to cope with losing a friend. This book shows you how applying kindfulness to the difficult side of friendship can help you mend your heart, move on and get the best out of those friendships that really matter.
