At different stages of our lives we have to be different.
We go child during the starting years. School days go perfect and remain the best forever. College makes one realize the magic of friendship and friends of this period remain for life in some cases. Early years of career needs your full attention whereas the later years of it demands your performance. Early years of relationship needs your time and the later stages of it needs your understanding.
At different stages of life different set of emotions and realizations wave at you. One has to be up to the mark and different from situation to situation to meet the expectations of life and people.
