　　Professor：

　　This week we talked about how important taking time off from work or school is for people's well-being. Some people believe they get the most benefit when that time off is structured: that is it involves planning in advance about what will be accomplished on that day. Others believe it is better to enjoy the day with no plan for how to spend it, In this discussion post please indicate which of those approaches to spending time off from work or school you prefer and why?

　　学生1I find it beneficial to do some advance planning for my free time. I live far away from my family so when I am getting ready to visit them during a school holiday, l always plan my time off from school very carefully. That way l have enough time to visit with each family member.

　　学生2Personally, I prefer not to make any plans for my free time. I go to school, and l have a part-time job each week. I make a schedule to be sure l can complete both my work and my studies. So when l have time off from work and school, l just want to relax with no plan.
