“If I am walking with two other men, each of them will serve as my teacher. I will pick out the good points of the one and imitate them, and the bad points of the other and correct them in myself,”—Confucius.
See the good in everyone you come across in life. No matter how good or bad they are; there is a lesson to be copied from them. The good lessons can be added to your life to make you a more informed person, while the bad ones can be used to correct those areas of your life that need adjustments.
Never let an opportunity slip off without making the most of it.
