If a certain information that you heard were true, what would you do to convince other people?

When I am sure that my information is true, I would rather insist on mine than others at first. However, I don\'t persuade everybody to believe what I heard. When I try to change someone who has a piece of wrong information, I figure out how close we are first of all. Whenever I push or say to someone that his or her information or idea is wrong, we can end up fighting and then giving each other the cold shoulder. Above all, I am concerned about whether my information is true, so I hesitated to give someone my true information. I can ruin someone\'s life, so I would try to give advice. The result is the individual\'s responsibility. For example, when the stock market was booming, people collected information to invest, and we asked each other which one was the potential to be on the rise, I invested in the company which my friend surely recommended, and I failed. We cannot be sure which information is true completely.
