What’s the difference between an entrepreneur and a businessman/businesswoman??

I require an agreement copy?
We are dealing into Fabrication of Airport handling Equipments.

I am 20 years old and attending a community college here in Florida. I am taking courses to obtain my business administration degree but my ultimate goal is to own my own business. I wanted to jump into a business venture but I realize that it would be best if I attended school and obtained a degree. My thing is that everyday I wish that I was done with school and I was running my own business but I know that it will only come in time. I want to be involved in a business and get some first hand experience while I am still in school. I have stressed the resources at my school ad have attended chamber of commerce meetings but still have not been presented any opportunities to do so. Does anybody have any suggestions or resources for me? Thanks
