Psychological self-control in investments. One of the biggest challenges for investors is to maintain discipline in the face of market fluctuations. Psychology shows that intense emotions, such as euphoria and panic, distort perceptions of risk. Strategies to increase self-control include setting long-term goals, using checklists before financial decisions, and automating contributions. In business, entrepreneurs also need self-control not to make hasty decisions in times of crisis. The psychology of self-control is therefore a central pillar to sustain stable growth.
