Garth Mackenzie recently befriended a 21 year old film photographer. A common love of 1990’s Mercedes-Benz cars drew them together. This 21-year-old guy is earning well for his age, but suffers from the common naivety around how to manage money. Now 45, Garth was inspired to write a blog article about investing lessons he wished he knew at 21 years old. This blog article was the inspiration behind an interview where Gizelle Willows – founder of Nudging Financial Behaviour – took over the role of host, and Garth became the guest.
