求翻译：一件事，就算再美好，一旦没有结果，就不要再纠缠，久了你会倦，会累；一个人，就算再留念，如果你抓不住，就要适时放手，久了你会神伤，会心碎。是什么意思？

One more thing, even better, once there are no results, do not dwell, long time will you weary, tired; a person, even if the mark, if you fail to grasp, we must let go at an appropriate time, long time you shenshang, knowing the broken.
