Take whatever you get from life, if you try to take more than what you want.. more than what you have.. then it will be a waste anyway. Not only will the extra stuff rot, you will have no need for it anyway..
Its like studying consumer behavior.. If you buy more than what you need, and more than what can fit in your shopping basket and shelf at home, the extra products will have no use and will hence rot. Hence it is best to understand your needs and not fake them to reach for more.
I guess this is my tribute to "The greatest Philosopher with Golden words", Ayn Rand and it is my way of asserting that the only religion or philosophy I follow is Objectivism.
