I’m growing up
I’m growing up day by day.I’m growing up into a strong-minded girl.Both my body and my mind have grown a great deal.
The wheel of life has rolled fast and past fourteen years.Before that,I was just a little girl.I loved toys and skirts.My friends and I always played in the parks and it was normal to have a fight with others.Gradually,I would rather talk to friends on the phone than play in the parks.I didn’t like colorful skirts any more.And I liked books instead of my toys .Previously,my friends and I must gathered together everyday,but now my good friends are just like stars.We don’t always see one another,but we know we are always in one another's heart.I’m growing up.We’re all growing up.
As time went by,I became taller and taller and my heart is stronger and stronger.I cried less and less,and I smiled more and more.The ups and downs in life made me strong.My growth experience tells me that life is a path full of frustrations.And we should always keep our heart facing the sun and it will bring us hopes.
It is said that,the power of life is the power of growth.I want to say loudly:I AM GROWING UP!To tell you the truth ,I am a girl who is sometimes worried about growing up.Despite that,I’m grateful that I’m growing up all the same.
