Picture Sisyphus happy, will you? You cant.
Let me tell you a story, their was a man named Mahatma Gandhi, he was born, and was shot dead by some random punk. Now, do you have respect for this man? No, not the killer, I am here talking about the man labeled as Mahatma; I guess no. Why? Because this is a Chinese wiener.... too short. Oscar Wilde said, "details are vulger." but ya so as the other 10 thousand videos on youporn; we love vulgarity. You can't sum up a person's life in one paragraph or one page, unless its a tragic story of a still born. Even an under archiver has lots and lots of to say.
Life by default(and in summation) is monotonous, we are part of a system which wants us to take a birth, learn, do things, reproduce, age and die. Unless you are Eminem or Rekha, coz these bastards don't age.
I think, Sisyphus delineate life of those who dont have aimS in their life. We have to understand the importance of plurality here, coz its the substratum of the dustup. SASSYfus chose that life, coz all he cared about was 'to live'. Now living is something different than having a life. Most of the people like Sassyfus just subsist, with no purpose but to live. Break free, have a drink with the Zeus(society), get a pink slip from him by telling him that you have your own balls, won't lug his anymore.
Btw, if you have read carefully, his boulder backchodi starts after his life was over(or meant to be over). So live your life till you have one, and care about the Sisyphus syndrome when your death arrives, which may be inferred as getting a job that you dont like, not being aware abt the book written by Vatsyayana and stuck with the missionary, or worse like not knowing you can switch hands(which btw gives different feeling).
