Vicky Reynal, a financial psychotherapist and author of "Money on Your Mind," told CNBC Make It that there are psychological reasons behind our spending habits, and many of these attitudes stem from childhood experiences.
Whereas someone who experienced childhood neglect may grow up with low self-esteem and act this out through money behaviors.
This could include feeling guilty when spending money because they don't feel they deserve good things, or splashing the cash to impress because they feel unworthy of attention.
A scarcity mindset means someone might struggle to enjoy the money they've earned and be anxious about spending it, Reynal added.
Alternatively, there are people who grew up with little but became wealthy, and are now very careless with money.
