Why don't most of us think a lot about life?

Most of us don't think a lot about life because we don't understand the meaning of life. L I F E is — Liberation from Ignorance and Finding Enlightenment. We think life is just to have fun till it is done. We all want to be happy. And we think happiness is pleasure, and so we are running a race to be an ace, thinking that success and achievement are happiness. We don't understand why we came to earth, why we got this human birth, what happens after death. We don't ask these questions because we think it's unnecessary. We think that even thinking about death is a waste of time and energy and it is meaningless. We don't meet a realized master who can lead us there, and our Karma is not so good that we can be liberated. But we can change this. If only we seek the purpose and meaning of life, our life can be transformed.
