On page 86 of the book Harvard Style, there are a list of Dos and Don’ts for college freshmen:
1. Don’t take part in too many extracurricular activities. (不要參加太多課外活動﹗）
Reason: Too many extracurricular activities will make time management more difficult and blur one’s life focus in college.
2. Don’t fall in love in the first year of college; at least, avoid it in the first semester. （一年級時不要談戀愛！)
Reason: Falling in love in the first semester will deprive one of the chance to get to know new friends.
3. Buy used textbooks.（買舊的教科書！）
Reason: College textbooks are very expensive and most of them are used only for one semester.
4. Get familiar with efficient study strategies. （熟悉有效率的讀書方法﹗)
Reason: There are too much to read or study, so it’s important to tell what requires intensive reading from what doesn’t.
