A schoolteacher Andrew Hallam built a $1 million investment portfolio on an ordinary salary; his strategy later became a bestselling book

Andrew Hallams financial journey started with a lesson from a bus-depot mechanic when he was 19. He continued saving while working through college and later became a teacher in British Columbia. Despite getting a modest salary, he adopted a really frugal lifestyle, paid off his student debt and continued investing. By 36, he had become a millionaire. By 40, he had become financially independent.
