Section
1 About Me
I think, according to the rules of etiquette, I should introduce myself first. My name is Aitmaganbetova Nailya
Temirgalievna. I was born in the city of Zhezkazgan, Ka-
Raganda region. I was a long-awaited, only and beloved child. My parents brought me up strictly, but they also spoiled me, I can't hide it. However, they divorced when I was four years old and my mother and I returned to her homeland in Eastern Kazakhstan, the town of Shemonaikha. This is where I spent my childhood. It's a rich land with a lot of greenery thanks to the fertile black earth. You can literally drop a seed here and a sunflower will grow. For me, this place will always remain dear and close to my heart. The steppes and meadows, followed by mountain cliffs and deep gorges, buried in the taiga, were forever etched in my childhood memory and imprinted in happy images of adolescence.
Perhaps these years were happy for me
Probably because my parents were able to keep their friendship; we never lost touch with my father. I went to see him during the vacations and he came to visit us.
I studied diligently, whereas no one was doing me.Mom was too busy working and taking care of the family, so I was always on my own from morning till night. That's why I understood early on what independence and responsibility.
Every day I sewed clean, pressed white cuffs to my school dress. I walked to school by myself, came back by myself, did my homework. Only then would I allow myself to go out and walk and meet my friends.
I was an excellent student until the eighth grade. I liked learning and absorbing new knowledge. I was always a leader in my class. According to the tradition of the "Military Training" subject, in all the classes selected boys commander. In our class, I was the commander. And, to everyone's surprise, we managed to win the marching contest! We were clearly marching with the toy weapons in our hands - I was in front of the line and the whole class behind me. We worked as a team. However, at that time I did not feel like a leader in the modern sense of the word. I took it for granted. That I am something different from others, I have understood only in institute.
Well, you got to know me a little bit better, and now
you can start the real, detailed story of my life. Enjoy the reading!
