The content of this paper includes everything that makes a positive life and that are positive conditions, emotions, performance, relations and experiences. In this paper I talk about ways how to develop positive thinking in children in preschool age, from the role of educators, but also parents. Finally, a community has a resounding affect on the child's development. The aim of this paper is to come to know and understand the concepts in the field of positive psychology, and awareness of our own feelings and thoughts in relationship with the individual. The importance of positive emotions is confirmed with an increasing number of studies that showed that positive emotions facilitate many social behaviors and thought processes, and they are also significantly improving our functioning. Developing of a positive thinking is important for a successfully dealing with the challenges and for transforming challenges into opportunities for growth and development. For positive thinking emotional processes are important such as awareness, expression and control of the emotions and cognitive processes such as optimistic thoughts, positive monologue and also a contestation of negative thoughts. The view of life on the bright side can have a positive effect on our feelings and actions. While due to the positive thought we can feel better, negative thoughts usually depress us and make us feel worse. Our feelings are directly related to our behavior and actions.
