Festinger's Law: This psychological concept states that 10% of life consists of events that happen to you, while the remaining 90% is determined by how you respond to those events. When something negative occurs, the key lies in your attitude and choices. You can choose to face it positively or respond negatively, and your attitude ultimately affects the course and outcome of the situation. When confronted with negativity, we need to actively adjust our mindset and be prepared to face challenges positively, as this is the best attitude.
