Time...A Benefit, or a Curse?

In response to Brittany Guntor's question, "If your life were suddenly free from a constricting time schedule, do you think you would get more done? Would your stress level decrease or increase?"... 

     I am one of those people who so incredibly relies on time. I get very anxious if I am ever late going somewhere, I live off of my agenda which has everything I need to do penciled out in front of me, and if I do not have enough time to get something accomplished, I get very frustrated. The most valuable thing I ever learned in taking five Advanced Placement courses while in high school was time management. This has helped me tremendously when I look at myself and my academic standing compared to some people I know who never seemed to learn these skills. To function in today's society, we do all need to truly master time, and often you hear people complaining that there is "not enough time in the day". I completely agree with this. We bog ourselves down so much with everything we have to do, where we have to be, and for how long we must remain there. We feel as if we never get to truly relax, for there is always something that needs to be done. It seems to me that this stress is taking a great toll on all of our bodies.
     If my life were free of such a time schedule, I do not think I would get much done. The closest to this state I have ever gotten is summer break, when for the most part, students are free from most of their stressful committments they had during the school year. But, in the summer I still use a calendar to write down important days or things I need to remember to do. I believe this is because I am so fearful of forgetting to do something important. So, if such an event as described by Brittany happened, my stress level might decrease for a while, but then increse when I realize what still needs to be done. Additionally, quite frankly, I do not think I would get much done without a time schedule. All school year I stress myself out so much that by the time summer or winter break rolls around and I do not have many committments, I do nothing. And it feels good to do nothing. Do you think our lives are too structured by time? If so, is there any possible way to change this?
