The first step is to figure out the usual costs of the things that you like the most (searching the internet works well). The next step is to figure out how often you run out of those things, or how often you would like to buy them. Then, you need to figure out how much money you usually get paid and when, and how often you get paid more money. After that, you need to figure out what money you already need to spend on the things you need in order to take care of yourself (food, housing, travel, etc.) and how often you need to pay for those things. Once you have all of this information listed, bring your list to a trusted adult who you know lives independently and might be able to help (we don’t want strangers knowing too much about your personal finances). Have that person help you figure out how much money you usually have left over after all your needs are met, and make a plan of how often you will have enough money to buy the things you want. If you keep finding that you don’t have enough money to buy the things you want as often as you want to, you might want to try to find more ways of earning or saving money, such as getting eating at home instead of going out to eat, or asking for more hours of work at a job you may have.
