Note: Education is, above all, the right to choose. The right to be with anyone you want, to live as you please, rest, as the soul lies, and to choose friends not because it is necessary, but because you are good and interesting with them. It is a flight, freedom from bondage and a great illusion of independence. It is a sense of self-satisfaction and the opportunity to build your life the way you want, not your parents / husband or especially zealous acquaintances. To serve only to oneself and sag only when this is deliberately a voluntary act, and not an attempt to save a marriage and stay with money, or status acquaintances and friends, many of whom have already figured out all the charms of your social parasitism. A person who has received an education abroad can quickly find a good job. However, he does not have to confirm his knowledge in addition. A foreign diploma is a guarantee that you will be recruited without any problems. Among the shortcomings is the cost of studying abroad. Only wealthy people can afford to teach children in the most prestigious universities in the world. In addition, a person entering a foreign university should have a basic language and also have some knowledge of basic subjects. It is also worth noting the difference in the cultures of different countries and domestic difficulties, because sometimes students have to look for work and housing in a foreign country.
