一、与其一直留恋错过的东西，不如学着去欣赏眼前的人和事。
it's better to learn to appreciate the people and things in front of you than to miss things all the time.
二、小时侯觉得一天好长，一学期好长，盼着时间快点过，长大后觉得，一年好短，一辈子好短，抬眼已是半生。
When I was a child, I felt that a day was long and a semester was long. I looked forward to the time passing quickly. When I grew up, I felt that a year was short and a life was short.
