What you will know is dependent on how much you want to know

How fast you learn on the job is tied to how much sacrifice you are willing to make

On the job training is learning while working on the job. You come into a new job that you know nothing about and then begin to learn and grow on it and become an authority and expert

Do your part. This is what counts

Hold on to what works for you

To do or not to do, the choice is yours.
