It means you dont care who you shaft in order to gain what you want.
Business minded just means you have a mentality for turning 1 into 4, 4 into 8, etc. thats both a good thing and bad thing. Shows you can hustle but it also shows your after returns.
I would presume that it simply means that someone is focused, logical, and has an aptitude for math. A compliment, almost certainly.
you are crazy because you don't know what emotions are, nor do you care about people.
