i found i fall behind ZhenYuan too much. he has been studying all the day. and i can't catch up with him. There are many things i need to study, he go too far before me. i feel i have pull away too far. from now on, i need to read many books and programm as much as i can.
he is just doing too much, i have to work hard. at first, as i begin to study c++, i should do my best to access to the grammar at the least time. i have no time, i have to finish the book in three days! that's my aim in the short time.
