First, begin with self-reflection. You can avoid overspending when you identify how it happens. Recognize that you have made ‘wrong’ spending decisions. Admit that you have gone beyond your budget.
Second, limit your temptations. Be determined to avoid situations that would lead you to overspend again. If you are used to go out for food and drink, consider going to free activities. They are equally fun but not very expensive.
Lastly, move on. Do not dwell on your shortcomings. Determine to take control of your overspending. Remember, you become a slave of what has mastered you. Do not be enslaved by overspending.
You can always draw something good out of your bad experiences. When you learn about your spending weaknesses, you can take the necessary step to avoid falling on the same trap in the future.
