Take off those cool looking glasses and be paranoid. Be very very very careful when you hire people to do a job for you. If you do not watch your back, they will surely rip you off. Don’t worry about being liked. It doesn’t matter if they like you or not. Be damned sure they respect you.
“Hire the best and trust them” does not hold any water. “Hire the best, and don’t trust them” is the new way.
