I do well in school, so people think I am smart. And it’s not true. In fact, three year ago I struggled in Grade 9. Later, I decide to get serious about school, so I made a few changes. First, I decided I would become interesting in whatever was being taught, regardless of that what other people thought. I also made up my mind to work hardly every day. After carry out these changes, I became active participant in classroom discussions. Then my test scores began to rise. How exciting! It seems to myself that being smart is simply a matter for making efforts and being interested.
