Use fears to keep you out of trouble, but don’t let fears deter you from goals when the fears are invalid. Use your intelligent mind to determine whether the fear you are experiencing is valid in preventing you from getting hurt, or whether it’s mis-applied by your reptilian brain and can be logically and safely ignored.
An example is a fear of people. If you were abused or bullied, it’s natural to develop a fear of people as a result of such experiences. However, it’s important to recognize that what you want is a fear of the specific individuals who harmed you, and avoiding those specific individuals is key to future success. That’s the practical side of fear. The impractical side of fear is avoiding all people, including those who aren’t going to hurt you. In those instances, it’s important to use your intelligent mind to recognize that the situation is different, and use courage and optimism to overcome that fear of people and develop meaningful connections with good people.
