We grow up enjoying our life and then do schooling with people who become our best friends and followed by some serious stuff in college.
We enjoy life like the freely falling rain drop and seldom think about our past and future or marriage or kids.
This is a time meant for enjoyment in the sense that although youngsters are accountable for their studies however there is no added responsibilities of earning bread and butter, running the family so on and forth.
At least I enjoyed my school and college time a lot and I owe it to my Mom and Dad.
So by far the best time in life is to live as a child getting pampered or as an adolescent with abundance of innovation and energy.
