1. Alignment. The resume will be more easily readable if everything left-aligns to the same spot. (Example: the second Bachelors listed in Education has a left aligned sentence, an indented bullet, and then another left aligned point. The third sentence shouldn't be fully left aligned because it indicates the start of another section.
2. Under experience, put what you did. If it doesn't directly apply, you can still show that you are a dedicated worker, a quick learner and have indirectly related experience in a professional environment. Use the bullets under your experience section to suggest everything you list under "Professional Strengths"
3. Toss professional strengths.
4. Pump up your skills section if you reasonably can. Is there anything else you've worked with you can throw in there?
5. Trim the activities. Honestly, nobody really cares and you could remove this entirely if you wanted to, but feel free to leave it. Just don't make it take up so much space.
6. (Last because everybody is so down on the Objective) Yes, you DO want an objective section, but use it for more than BS. This is your chance to tell the company what you bring to them and how you can contribute. Keep it completely honest but use it to impart your enthusiasm for what you do and the role you want. Describe the environment you want to be in. Help the company figure out if you're a match.
SAMPLE:
"Find a position where my financial and analytical skills can be put to effective use to further company goals. I thrive on a demanding corporate environment (or laid-back small-business environment etc.) where projects have a high impact, either behind the scenes or up front (creative spin, high visibility etc.). My ideal position would utilize my current skills and provide a variety of challenging opportunities."
