The good news is that anyone can make a budget, regardless of their personal financial circumstances.
Decide what is important to you in the short and long term, and make saving for those goals a part of your budget.
A good place to start is to track your everyday expenses. Spend a few weeks tracking what you spend to identify your spending patterns.
Remember that your needs and wants may change over time. The answers to these questions become clearer once you have set priorities for your money.
The basic principle of a budget is to consciously spend less than you make.
