Her savings tip, which is part of a larger campaign by the Council for Economic Education to promote financial literacy, is to spend time each week going over your expenses and savings. “If I don’t pay attention, I’m likely to spend more,” she said of her own experience. “Ignorance is not bliss. Inaction is not bliss.”

As a freshly minted Ph.D., Lusardi said she made her own missteps when it came to saving. “I didn’t take advantage of many opportunities, like maximizing a 401(k),” she said.

“We all have a great asset, which is time. Time works in our favor because of interest compounding.”

“The young have incredible opportunity to build wealth but we don’t take advantage of it,” she added. “That’s the biggest challenge.”

Other money-saving tips will roll out on social media throughout the month with the hashtag #MySavingsTip.
