My secret

I will tell you a secret. And you will say it
I do tell you because I just want to be fit.
But I think you should not be so clever and smart.
Maybe I am a wonderful maker of art.

I can not at all draw. Now the secret is told.
I am terribly weak when a pencil I hold.
But the drawings I make, are all pretty well fine.
Now I proudly have told you the secret of mine.
