Joe Mihalic is a changed man. In 2011, he led the typical the Harvard-MBA lifestyle, with a lucrative job at a big tech company, a house in the suburbs, two cars and a motorcycle, and frequent travel—but he felt trapped. “I wasn’t working at a company I loved or in a job I loved. I wasn’t living a life I loved,” Joe says. So he changed his life drastically, becoming a minimalist. And that decision led him to pay off $90,000 in student loan debt in just seven months.

Joe, who lives in Austin, Texas, chronicled his journey to payoff success in his blog No More Harvard Debt. His posts resonated with many young grads, and his blog went viral in 2012. Now debt-free and an operations manager at a company he loves, Joe says he’s found inner peace. But he hasn’t let go of his frugal lifestyle— his work shoes attest to that. While paying down his loans, he wore the same shoes, even as holes appeared in them. Today, he won’t buy a new pair of shoes until the soles wear out.

Joe didn’t take every possible road to pay off his student loans—for example, he didn’t refinance, or take advantage of a student loan forgiveness program. But his “all in” approach offers many takeaways for MBA grads facing mortgage-sized loan debt.

It’s not exactly news that millennials are marrying later than the generations before them. But to give you a sense of just how differently they approach the tradition from their parents, in 1962, nearly 60% of 18- to 30-year-olds were married. Today, just 20% of people in that same age range have tied the knot. As such, they’re older than their predecessors were, too—whereas the average woman in the ’70s was barely 20 when she walked up the aisle, today she’s over 27.

Waiting to be more mature and financially stable before marrying is not a bad thing, and could help to explain another trend on the rise among this age group. Before saying, “I do,” millennials are asking for prenups, in larger numbers than before. In fact, just over 50% of matrimonial lawyers attest that the number of millennials requesting prenuptial agreements is on the rise.
