Can you do it?

"Can you do it?"
The first shadow asked me,
I answered,
"Yes, I can do,"
After a while......
The second shadow appeared
And he also asked me,
"Can you do it?"
I confidently said,
"Of course I can do it,"
Soon the third shadow flashed
In my superior inner eye
And whispered to me,
"Dear friend!
You can surely do it,
You really deserve so."
