change in perception.

once i thought..
life is all about enjoying every moment
living everyminute to the fullest..
experimenting new things..
and then i lived a life
when everday was a bliss,.
heaven had opened its doors for me..
and now i think..
enjoying everymoment how s tat done?
living everyminute.? experimenting new things..
without anyone to share..
hows tat done..
with loneliness embracing everysecond..
and now i live a life
grieving over the past
the mistakes i made.. they are unknown to me..
could i change it?
can i go back to those days..
its just meaningless..
