Do you know me?

Do you know who I am?
I am hard to discourage;
I am a bundle of determination;
When I set out to do something,
I let nothing stop me;
I make sure I do what
I want to do;
That’s me;
I never give up;
If I consider it important
I do it;
I have a winner’s attitude;
I am firmly convinced
I am bound for the top;
And that I will get there.
I also work hard;
Maybe I work not hard;
But very hard.
That’s me, short and simple.
