In my childhood, my parents sent me to learn Chinese calligraphy. However, things are quite opposite to their expectations. Not only I get bored with hours of practice but also I doubted about the valuable of it. Nevertheless, when I entered high school, write calligraphy proved both essential or beneficial. It was at that time when I realized how important it is to master a certain skill.
Judging from my own experience, I want to say a few word to those children who have a same trouble as I did. Do not refuse to learn a skill when young, as at the long run you will find them helpful.
