Now that you have the words on paper, go back to each list and think about which items are relevant to your target job. Cross out those things that don't relate, including entire jobs (like flipping hamburgers back in high school if you are now an electrical engineer with ten years of experience). Remember, your resume is just an enticer, a way to get your foot in the door. It isn't intended to be all-inclusive. You can choose to go back only as far as your jobs relate to your present objective. Be careful not to delete sentences that contain the keywords you identified in step four.
