My favourite sport

Hi! it's me again. there is plenty to do after school hours, particularly sport which i enjoy most. I love many sports but best of all football. Almost all my friends are in our football team. We train hard and we often play for the school in various regional youth tournaments. Our coach has taught us all rigid rules which must be strictly observed. The last game we played ended in a draw - 3:3. And though we know the famous Olympic quotation "The most important thing is not to win, but to take part" , we all want to win some day.

I do sport every day. After school on Mondays I go running with my friends for about an hour. Then i go to the swimming pool. Swimming is an excellent way to keep fit. It makes your legs and body strong.

Pele, the greatest footballer of all time, is my idol in football.

He became a world star at the age of only 17, when Brazil first won the world Cup in Sweden. He played in four World Cup competitions and scored over 1.200 goals in his career before finaly retiring in 1977. In 1994 he became Brazilian Special Minister for Sport.

I'm happy that i have take up sport. It helps me to become fit and i hope it will help to develop confidence, persistence, responsibility, and courage which are most important qualities to become a personality. Besides sport gives you a sense of duty, a sense of collectivism and discipline.
