“A Lannister always pays his debts.”
Growing up, Tyrion Lannister learned that lesson from his father.
Whether the debt was in promised payment for a deed done, or whether it was revenge for a debt of honor, that theme is something associated heavily with Tyrion Lannister in the A Song of Ice and Fire books (made famous by the HBO show Game of Thrones).
Warning: There may be spoilers, since this piece is based on the books, and not the TV show.
Even though it might take time to engineer your plan to get out of debt, it’s important to do what you can to reduce your obligations, and Tyrion Lannister is a perfect example of this.
