It's not that wearing a polo is professional, but you will be around the same high-level people as you work with.
Yeah, our views clash somewhat but I am kinda different from most people. My parents are small business owners and so I got into many arguments in school with people who said that work wasn't fair and whatnot. I also have my whole life pretty much planned out as far as a career. I am going to graduate from an Engineering school in 4-5 years, Work for someone else as an engineer for 10 years tops, then either own that business or start my own. I am also studying about stocks and property investment already at 18 years old.
