Butter ending with fly

Times... is just like butterfly
You never notice when it goes by,
Working too hard, hardly notice beauties at your sides..

Sometimes, you're like a fly,
Circling around some shits, and never know why,
As the fate decider, toying with your tries,
You loss the faith to make another smarter choice.

Sometimes you wander into deep thoughts,
At times you shudder at your failing shots,
If life is simple, then why is it so cruel,
To think of hardwork that's never rewarded.

They said there's fate, they said there's desparate,
Time is just like a ticking reminder...
