Should Have Done Better

Someone once said,

"I tried my best because I know, in the end it would be MY fault if I can't do it."

So here I am, banging my head to the wall, thinking that those words are just soo right. It was my fault. I could have done better. I should have done better. 

And now the cost is... arghh. Speechless. What else can I do? What else should I say? I did it, so I will pay for it.

Aaaaargh! I could have done better! :(
