I still see an error.

I strive harder than I can embrace
In my mind, failing is a disgrace
Pain the price I have to pay
Sadness nor tears may be displayed
At times I want to lose it
One word that isnt an option is quit
In my eyes I still see an error
One correct step I achieve, still no one will care
One goal in my eyes is perfection
In a mirror I never see my reflection
The more numbers go down
The higher I can leap from the ground
Others may see the beauty outside
But never can tell how imperfect inside...
