I'd think hard before going to grad school. Worse case scenario you spend 2-years getting a MBA, thousands of $ in debt, need a part time job during school and you will probably miss any great opportunity that pops up while attending school.
I've own/owned a few successful business (including one that has serviced the Pharmaceutical Industry for 28 years) and I've never been overly influenced by an advanced degree when hiring a first time job seeker. What impresses me most is someone that works his ass off, has a positive attitude and demonstrates a willingness to do whatever it takes to get the job done. If someone tells me they have been working at Home Depot, waiting tables, cutting lawns etc. while looking for their first break - that impresses me. There are plenty of other jobs in the Pharmaceutical biz besides carrying a bag - unfortunately most of the new opportunities are in NJ. A great field is Medical Education/Marketing Companies. They help educate docs on new meds and most projects involve traveling to resorts, hotels, convention centers etc. and conducting meetings. FL is one of the most popular meeting destinations for Pharma and companies are always looking for good young talent - plus lots of young attractive woman work in the field = bonus. Good luck and stay positive!
