Every step of our life have requirements to meet. Sometimes life requires from us to drop some traits, attitudes and ambitions in order to make the next step of life.
Compared to life, we came as humans into life without cloths or dresses but along the line we have to wear cloths and dresses in order to fit into the world.
But as times goes on, these cloths and dresses would be of no value to our dead bodies when we leave the world.
I think it will be good if we willingly give up on some friends, relatives, ambitions, behavior and believes in order to be in trend with our constantly changing world
