Whenever you have been asked this question, please don't use the adjectives like a hard worker, dedicated. As the interviewer can't judge you then and there whether you are a hard worker or not.

So this should work:

And I am willing to learn every bit of that work and I am going to execute every bit of that work as I learn and go through the stages.
