When writing use plenty of resume power words to convey that you're a pro-active applicant who can get things done. These are particularly effective when used in your cover letter, summary, and accomplishments/job description.
Think of yourself as a best-selling author. You want to pack your story with powerful descriptive words that will keep your reader intrigued. You're doing the same thing with your cover letter and resume but you're telling your own story instead of a fictional one.
If you haven't added in power words to your resume yet, you'll be pleasantly surprised by the results. The resume even reads better when you read it out loud.
A quick google for 'resume "power words"' will give you longer lists, but here is a quick one to get you started.
