The very secret of life for me...was to maintain in the midst of rushing events an inner tranquillity. I had picked a life that dealt with excitement, tragedy, mass calamities, human triumphs and suffering. To throw my whole self into recording and attempting to understand these things, I needed an inner serenity as a kind of balance.
