There are many types of life people live. Some people are chastened by the certainty of impending death, some live following the epicurean motto (eat, drink and be merry), some people live without giving it a thought, and Hellen Keller thinks that we should love our each day as if it was our last.
Those people who live subdued and gloomy life due to the certainty of imminent death, live life wrong way. They will be down for the most of their time and won’t be able to exploit their life for fun. Fun will be meaningless for them.
Those people who live without giving it a thought, though unwitting, someway live their life better than the above mentioned.
I have several objections with the Hellen Keller perspective. You can not live each day as if it was lost. It’s not practically possible. You won’t be reading this and I won’t be writing this. People won’t be giving each other any love and compassion, they will become selfish and all sorts of problems will emerge in the society and we will become narcissistic and self-centered.
I think the best way is to follow the epicurean motto, live each day with delectation and happiness without any regret. Be happy all the time and fully exploit your life. 😀 . Peace.
