Young and carefree!!

I was then 12 yrs. old, nearly teen
I laughed as loud as i can..
cried bitterly, i remember then
I was then 16 yrs. old
happy... as i go out with my friends
busy... when I studied my lessons
lonely... when unsatisfied in grades
thats my youth young and carefree
I was 19 yrs. old, my last teen age
sweet smiles i gave to my old folks
big headache when i turned back to my parents
cry out loud day and night when my ist love failed
just stopped when i got tried...
and now...
I was then 20 yrs old, but still young
I have many plans for future
but dont know how and where i should start?
I have commitments in life
that getting more meaningful
but still dont know
when it will last
yet, I know I should live my life
happily, young and carefree
