To sum it up: There's something to be said for appreciating the guilt trip. It's a journey that triggers remorse and causes you to take responsibility for unethical behavior. Guilt is often the first step to self-reflection and self-improvement. It causes you to slow down and partake of life's pleasures without greed. Guilt helps you maintain high standards and live a values-based life.
Go ahead, embrace guilt the next time it visits. And don't forget to say thank-you!
