Last week I watched a documentary on the rock band, U2. From The Sky Down, tells the story of how U2 forged their pivotal album Achtung Baby from the fires of their own personal hell. It offers a rare insight into the creative process in rock music. For me though, it reveals something greater. It shows how to find solutions where there don’t seem to be any and how we can generate our greatest moments of genius from our darkest hours.
