The goal of education and the entire educational process should be a fully "functioning", integrated, thought-out, and satisfied person, according to the current development characteristics. This is possible only within the framework of a holistic approach, which perceives the child not only as a cognitive/rational being but as an indivisible whole of a physical, mental, and spiritual dimension.

The holistic approach has been promoted and encouraged by UNESCO and the European Commission for decades, and it is time to introduce it into Slovenia's school system. Only comprehensive consideration of the child leads to understanding his personality, needs, hardships, wishes, etc. This will make it easier, more efficient, and faster to limit children's mental health problems, as there is an increasing number of violent behavior, chemical, and non-chemical addictions among young people. In Slovenia, we have entirely neglected mental health for children and young people.

The latest research shows that teenagers and children spend an average of around 6-7 hours a day in front of the screens, which has highly negative consequences for mental health, brain development, cognitive abilities, and concentration and leads to anxiety, depression, apathy, self-harm

behavior, lack of empathy, aggressiveness, development of addictive behavior, speech problems, reduced coordination, and physical abilities, obesity, diabetes, low self-esteem, confidence, etc. Screen and social media addiction have become so daily and "normal" that the adult world doesn't even notice it anymore.

Albert Einstein said: "A man who considers his life to be meaningless is not only unhappy, but he is barely able to live." This means that a man who is internally fulfilled and sees meaning in life is also internally strong. This is important for mental health and a quality and satisfying life.

The scientific monography Holistic approach in the field of upbringing, education, and mental health, which was created in the framework of the ARRS project Holistic educational process and strengthening of mental health, was co-created by authors who are experts in the mentioned fields and includes sixteen chapters and the Proposal for a strategic plan for the renovation of V-I of the educational system in the Republic of Slovenia.
