Remember that most of the time your CV wont be read by the manager you send it to, but by some flunky who acts as a filter. They will dump 90% of the CVs in the big round filing cabinet. Your CV, and it's covering letter, have to stand out from the crowd.
The problem is you've done almost nothing. Your CV is going to be sparse. If you did a paper round, stacked shelves in a supermarket after school, tutored kids while in college, did bar work, did voluntary work, put it on the CV.
You have a part-time job now - put it on the CV. Find a second one, put that on the CV too. Having 6 months of low-paid jobs on your CV is far better than having 6 months of playing WebDip for 15 hours a day (I cleaned windows, just me, a bucket, a squeegee and a ladder - that went on the CV).
