Cassie Holmes has spent her career studying how we spend our time and why it may matter more to our happiness than money. But her own relationship with money started with an argument she overheard as a kid.

Cassie is a professor at UCLA's Anderson School of Management and the author of the bestselling book Happier Hour: How to Beat Distraction, Expand Your Time, and Focus on What Matters Most.

She talks with Chris Hill about how that early unease shaped her approach to work, spending, and time, as well as:

• A summer job that taught her something her Ivy League education hadn't

• Why her business school colleagues rolled their eyes at studying happiness (and what changed their minds)

• The one thing she spends money on that lines up perfectly with her research

• Her biggest money regret, and why it isn't something she bought
