College is a perfect time to get involved in volunteering for a cause. No matter what your passion is, there is a movement for you to plug into. Happy people give give give with all their might, and studies have shown those who do experience a similar “drug-induced high.” Ask most people who volunteer regularly why they do it, and they’ll probably say something along the lines of “I love the feeling I get from helping someone else out; once you see the results of your hard work, it makes it all worth it.”

 大学是个为了一个目标参加志愿活动的绝佳时间。不论你的热情何所在，总有一项合拍的运动适合你参与。快乐的人总是尽自己所能的给予付出。并且有研究表明这些人会感受到类似于“药物刺激下的飘飘然快感”经历。

 如果询问大多数定期参加志愿者活动的人为何参加，他们很可能给出一个类似这样的答案，“我喜欢那种我能够帮助别人走出困境的感觉。一旦你看到了你努力工作的结果，就会知道这一切都值了。”
