The hobbies in our lives.
Probably, every person has some hobbies in life. Someone dreams of becoming a musician or artist, but some people can fully devote himself to scientific activity. People can choose how to find their talent and develop their skills, and this is very important because if you have a great desire to work hard and then you can achieve success.
I would like to say a few words about my hobbies in my life. I love to read books, I could read 5 years. In the childhood I liked poetry, but when I grew up, I tried myself to write them, and I think I'm pretty good at writing poems, because my work was published in a local newspaper. When I was 11 years old, I studied drawing and I participated in different exhibitions quite successfully, I liked to do it. Especially, I liked to draw and paint, I remember that I drew a bunch of tulips for my mom as a gift for her birthday. When I was able to learn how to draw, it helped me to be focused and attentive, but at the same time, this activity calmed me and made me smile. When I was 13 years old, my parents bought me an electronic synthesizer, I began to make music. I played a lot of music, and when I was able to play a few songs without making mistakes, I was very happy with their success. But unfortunately I gave up playing on the synth, because I had little free time. But I think I am definitely going again to play a musical instrument, because I can't imagine my life without music. I also want to say that I love learning new and interesting things. I'm interested in history, mathematics and biology, and I like to study foreign languages, I want to learn to speak French, and I want to work abroad and travel around the world.
I would like to wish all people, so that they can enjoy their hobby and that they were confident that their favorite activities will make them happy.
