While information gives you access to what is already known, it in no way guarantees you will know what to do with it. One action may be appropriate given certain information. Yet, the same information in a different situation may require completely different actions.
Unfortunately, many people take information and try to use it the same way in all situations. Take, for example, the notion that all men cheat. How is that information applied to men who do not engage in infidelity?
If a person has not learned how to learn and change, they may never experience the fact that all men do not cheat, even when they are with a man who does not cheat. If you do not develop the skills to learn and change, there are many possibilities in front of you that you may never experience.
Allow yourself to develop a new perspective. Speak openly with people who do not support your point of view and understand theirs instead of yours. Then find the common ground between the 2 of you. Learn subjects that have little interest to you and look for the relationship it has with what you already know.
