The authors Kristy Shen and Bryce Leung are part of a movement called Fire that encourages people to save intensively to retire early
Growing up in poverty in rural China, where her family collectively lived on as little as $0.44 a day, Kristy Shen learned to make decisions based on pragmatism rather than passion from a young age.
On her first ever trip to a toy shop aged eight, after her family moved to Canada, she declined the offer of a teddy bear in favour of a cheaper one and requested that her father send the remainder of the money to their family in China. As a teenager, she chose to be a computer engineer, ignoring her dream to be a writer, based on a formula she devised to rank the best value university courses based on tuition fees versus future pay. And as an adult, any domestic disagreements with her husband, Bryce Leung, are generally won or lost based on who makes the best mathematical case.
