How can i make sure i'm taking care of my financial health as a teenager?

Pay with cash, not credit, get informed, learn how to budget, start an emergency fund, save for retirement now, control your taxes, protect your health, protect your wealth. To begin with, write down your income and all your expenses, and then subtract expenses from income to determine your discretionary spending. At the beginning of each month, set a budget to allocate how discretionary funds are spent. Keep track of your spending throughout the month and, at the end of the month, determine if you stayed within budget.
