On 29 January, we will exit the Year of the Dragon and enter the Year of the Snake. In the Chinese zodiac, people born in the Year of the Dragon are said to be powerful and optimistic. In contrast, those of a serpentine year are wise masters of reinvention, able to shed their skin amidst change. Past years of the snake have indeed been transformative: 1929, 1941, 1953, 1965, 1977, 1989, 2001 all saw war, economic pain, or political and financial instability.
