In my opinion, the high school years are very important in training a young person, shaping his character and preparing him for life.
First of all, during the four years of high school, the adolescent focuses on a certain favorite field, learning everything necessary to practice a profession in that field. In addition, the adolescent learns useful things related to general culture, through auxiliary subjects.
Second, through extracurricular activities, the adolescent develops his creativity, thinking and reason. He has the chance to spend his free time in a useful and pleasant way. Also, by interacting with other people, the adolescent learns to work in a team and develops his social skills.
In conclusion, according to the above, high school years have a great impact on the adolescent, shaping his personality and helping him mature.
