Budgeting. It's not a word that many of us like to hear, but it's nonetheless a vital milestone in becoming a young adult. Tracking your spending and creating a budget plan will allow you to spend money based on your priorities instead of frivolously spending it on stuff that you don't really value.
A few of the responsibilities of being an adult include paying your bills on time and sticking to a budget. That's the only way you'll be able to reach all of your financial goals, like traveling, saving up for a big purchase, making a career transition, and putting away money for a comfortable retirement.
