A model of an optimally functioning person (OHF) is proposed based on an interdisciplinary approach and the principles of integrity, harmony and order. Five main integral internally differentiated personal characteristics (actualization, improvement, compromise, consistency, anti-entropy) are established, built on 18 necessary and sufficient factors. The anti-entropy factor is fundamental to ensure optimal performance. An analytical expression for the balance of the entropy of a biological system is given. The model is available for self-education of an optimal lifestyle.

The article presents a model of professional improvement of teachers of additional education for children, built based on the interaction of methodological work and additional education and PC (advanced training).
