Please don't say "i am 25 and i am wondering if it is too late"..
if you are kind enough to let people who are much much older than you live well......
Dear Charlie:
Many people said that when a person has grown up,his or her character and other traits will be very steady and hard to change. So you know,25 years is really not a short time. I know I have some drawbacks in my character and want to improve myself very much. But sometimes I'm just afraid that something is hard to change and then feel frustrated.
There is really a long long way to go. I will try.
