How to avoid getting back into debt?
With your windfall, you've been given a second chance. You've become debt free again, and get to start over. Here is what I would recommend from this point on: Decide that you want to remain debt free. It sounds like you've already done this, since you are asking this question. Commit to never borrowing money again. It sounds overly simplistic, but if you stop using your credit cards to spend money you don't have and you don't take out any loans, you won't be in debt.  Learn to budget. Here is what is going to make being debt free possible. At the beginning of each month, you are going to write down your income for the month. Then write down your expenses for the month. Make sure you include everything. You'll have fixed monthly expenses, like rent, and variable monthly expenses, like electricity and phone. You'll also have ongoing expenses, like food, transportation, and entertainment. You'll have some expenses, like tuition, which doesn't come up every month, but is predictable and needs to be paid. (For these, you'll can set aside part of the money for the expense each month, and when the bill comes, you'll have the funds to pay it ready to go.) Using budgeting software, such as YNAB (which I recommend) will make this whole process much easier. You are allowed to change your plan if you need to at any time, but do not allow yourself to spend any money that is not in the plan.  Take action to address any issues that become apparent from your budget. As you do your budget, you will probably struggle, at first. You will find that you don't have enough income to cover your expenses. Fortunately, you are now armed with data to be able to tackle this problem. There are two causes: either your expenses are too high, or your income is too low.  Cut your expenses, if necessary. Before you had a written budget, it was hard to know where your money went each month. Now that you have a budget, it might be apparent that you are spending too much on food, or that you are spending too much on entertainment, or even that a roommate is stealing money. Do what you need to do to cut back the expenses that need cutting.  Increase your income, if necessary. You might find from your budget that your expenses aren't out of line. You live in as cheap a place as possible, you eat inexpensively, you don't go out to eat, etc. In this case, the problem isn't your spending, it is your income. In order to stay out of debt, you'll need to increase your income (get a job). I know that you said that this will slow your studies, but because you are now budgeting, you have an advantage you didn't have before: you now know how short you are each month. You can take a part time job that will earn you just enough income to remain debt free while maximizing your study time.  Build up a small emergency fund. Emergencies that you didn't plan for in your budget happen. To remain debt free, you should have some money set aside to cover something like this, so you don't have to borrow when it comes up. The general rule of thumb is 3 to 6 months of expenses, but as a college kid with low expenses and no family to take care of, you won't need a huge fund. $500 to $1000 extra in the bank to cover an unexpected emergency expense could be all it takes to keep you debt free.
