The document provides 5 reasons for maintaining vigilance over one's credit score: 1) Correct any inaccuracies reported in credit reports from Equifax, Experian, and TransUnion to improve the score quickly. 2) A longer credit history improves the score. 3) Keeping the credit utilization ratio, the amount owed versus the credit limit, below 20% can boost the score. 4) Taking out a personal loan from family or friends to pay down existing debt may help. 5) Continually focusing on one's credit score is important.
