American personal finance expert Jesse Mecham shares four simple rules to help people understand their expenses and make smarter financial decisions.

Financial anxiety can affect anyone, regardless of how much money we make.

Whether we are stressing about next month's rent, unexpected expenses, or the fact that all our friends seem to be going on luxury vacations, money is often on our minds.

In 2004, American author and financial expert Jesse Mecham developed a system to allow him and his wife to graduate and start a family on a single income.

Mecham's system turned into You Need a Budget, a company that helped thousands of people transform their finances.

In this 2018 book, named after his company, Mecham explains how following four rules can ease our financial anxiety and bring us closer to the life we want.
