Spending wisely means thinking before you buy. Ask yourself: "Do I need this, or do I just want it?" Needs are things you must have (food, shelter, school supplies). Wants are things you'd like to have but can survive without. A great trick is the 24-hour rule — wait one full day before buying something non-essential. If you still want it the next day, it might be worth it! Also, compare prices before buying and look for sales. Smart spenders get more for their money.
