Wait and see a big surprise for you

Are you the one
Who said I was finished?
Who dismissed me?
Who waved me off?
Who said it was over for me?
Did you say I was finished
And it was all over for me?
That nothing
Could still come out of me?
You are mistaken
If that is your thinking,
You are mistaken.
I’ll surprise you;
I haven’t even begun yet.
Wait and see me;
I have a big surprise for you.
