Plants usually like lights, so when they are planted in dark places, they stretch their branches toward lights. But some others like darkness and grow well in the darkness. Similarly, there are two sorts of the mind of men. Some follow goodness, while the others evils. Some people are frustrated in the face of difficulties and troubles and go astray during their whole life. But some others overcome the same difficulties with perseverance and try to help and strengthen those who are in the same troubles. I wish you understand your life is different depending on the attitude of your heart, and follow only goodness like plants that stretch their arms toward lights because they love light.
