Your resume is a reflection of you. I have read thousands and you need to assume that the employer or recruiter reads hundreds or thousands. You have got to make yours noticeable. We have all heard the expression keep it simple. Some resumes read like novels. In sales roles there are may flavours-inside or outside, retention or acquisition,b2b,b2c and everything in between. It's important to let the recruiter or employer know where your strengths lie. This can be done in point form. Your time is valuable so you want to be in front of the right employers and they for sure want the right candidates in an interview.
Assume that not all recruiters and employers read your resume from top to bottom at first glance. You need to get your resume noticed. You need to list your accomplishments, prizes and promotions. It's not bragging, it's sales!!
I once interviewed a 43 year old guy who had a 1 page resume (someone told him that was a good idea) that showed 3 jobs. I spoke to him on the phone, liked what I heard then interviewed him face to face. He was great. I told him that his resume was like a black and white tv and he, in person , was like an HDTV.

Another thing, get rid of those funky email addresses that you once had in university such as funkygirl@ or partyguy@. It doesn't look professional. You might want to use plain white paper when mailing but most often you'll be emailing yours.
Most important tip, DON'T EVER LIE ON YOUR RESUME. It always comes back to haunt you. Don't embellish the truth. It seems fairly simple as advice but needs to be said.
You should also leave some information for the interview so your accomplishments in elementary school may not be altogether necessary.
