When Heike Faller’s niece was born she began to wonder what we learn in life, and how we can talk about what we have learnt with those we love. And so she began to ask everyone she met, what did you learn in life? Out of the answers of children’s writers and refugees, teenagers and artists, mothers and friends, came 99 lessons: that those who have had a difficult time appreciate the good moments more. That those who have had it easy find it harder getting old. That a lot of getting old is about accepting boundaries. And of course, as one 94 year old said to her, ‘sometimes I feel like that little girl I once was, and I wonder if I have learned anything at all’.
