George Top 10 List

Every month, I will ask George to write down his top 10 things he likes to do. He can write down less than 10 items. But he can not write down more than 10 items. Only the items staying on the top 10 list for X months, then I will try to satisfy his desire. The X is determined by his age.

On September 24, 2006, George wrote down his top 4 as his top 10 list.

1. Chess
2. Piano
3. Drawing (using chalk)
4. Da Gupiao (stock investment)
