Human's life for three days: Yesterday, today and tomorrow.
Do you like the famous song “Yesterday Once More”? It is a song which recalls the memory of yesterday. Memories are so sweet but they have gone with the wind. As time passing by, things changed. We grow up. We have to say goodbye to the childhood and face our lives.
When I went into the society, I didn’t wonder time had gone, because I knew we grew up and we are not children any longer. We should think about future instead of being obsessed in the past.
Yesterday was yesterday. It won’t come back, but I still have today and tomorrow. Today is the very minute and second I have now. Yesterday has already past. We are looking forward to today and tomorrow.
Today is the most important day because today is the foundation of tomorrow and the result of yesterday. What we didn’t complete yesterday becomes the root of regret and remorse of today. Tomorrow is great because everything is possible; however, the key to tomorrow is today. What if you can not take good use of today, how can you guarantee that there is a brilliant tomorrow waiting for you?
Yesterday has past. Tomorrow will befall us. The most important thing is every second we own today.
