human-made systems are bound to be imperfect

What I see around me are different organisations and systems working....many of them artificial, that is, human-made. These include society, family, education, marriage, politics, administration and what have you. Once we finish creating a system, we find ourselves or some of our brethren taking upon themselves the task of making it free from errors and limitations. This correction-making is a continuous and unending process : perfection cannot be achieved in these artificial systems. We can only endeavour to make them nearer to perfection. The day perfection is achieved, they will cease to exist. It is like that concept of Limits in mathematics wherein if x limits to zero, x will try to be as close as possible to zero but never equals zero, for then it will become meaningless.
We should rejoice in this fact rather than regretting it. This continuous struggle for excelling and ironing out the creases is what keeps us human beings engaged and gives many of us a purpose.
