What would you do, if you had a bad undergraduate GPA from a Top 10 university, 1.5 years of random work experience, a sales job you hated and felt like was a waste of time, and the biggest passion and desire to work for a top company in a luxurious setting (in the shortest period of time)?
first thing - get that goal out of your mind. what do you mean work for a top company in luxurious setting?
next - quit the job you hate and get a job that you think you may enjoy. work hard a few years and make a difference at your workplace and the community you live in. then come back to the question of what you wish to do with your life. you will have a better idea of where you want to go and how to get there.
there are no short cuts.
