Erika Kullberg graduated from law school with over $200,000 in debt but paid it off in two years. Now, she's trying to help young people get ahead financially and learn their rights as consumers.

Last September, she made nearly $6,000 sharing financial advice over social media. Her most popular content features her “reading the fine print” of companies' terms and conditions to help people save money.

In one video, which has received over five million views, Kullberg explained that if a pair of Nike shoes develops a tear within two years of the shoe's manufacturing date, the company will often provide a new pair or a gift card for the same value. She's also detailed other companies that have similar policies.
