The chief beauty about time is that you cannot waste it in advance. The next year, the next day, the next hour are lying ready for you, as perfect, as unspoiled, as if you had never wasted or misapplied a single moment in all your life.
At the end of the day it's not about what you have or even what you've accomplished... it's about who you've lifted up, who you've made better. It's about what you've given back.
人生没有捷径，只有脚踏实地。
