Is a cycle:we are born;we are babies and we dont know the meaning of life , meanwhile you are growing you are 8-10 years old and you start to understand what is the meaning of some stuff.
You get to the puberty and everything seems an exageration; you are a teenager and all you think is in having fun, living life at its extreme, you are an adult and you think about your work; you are old and finally you die, thinking that all you did is useless know; if you get to be rich when you die you die poor because you cant take the money with you,and you think that it didnt help you to have money because you bought books but not the knowledge, medicines but not the health, a house but not a home, or you think what would have happen if i did something more, anyways you die unhappy eventhough you had all the money in the world, because you wont have it anymore and it was useless all the time you spent making it up.
And you never found what life really means.
