Very good attitude! And good question.
Resumes used to be lists of accomplishments but they have evolved. Now what employers are looking for is how can this potential employee help me, the team and the company. If you created a new, more efficient process or figured out how to shave 10 seconds off of an existing process that shows employers that you can make a difference. Even if your only job has been fast food, if you figured out how to make fries faster, it shows initiative and the ability to think outside the box.
Employers also know that if it is an entry level job, you probably haven't had much of a chance to make a difference. So don't get panicked about it.
What you need is to use strong action verbs such as drove, created, etc. You can use your projects from school. If you had a group project did you lead it? Did you keep the team focused?
See if you can get a few industry managers to look over your resume and critique it.
Best of luck!
