Can potentially make more money in less time, and control when someone stays.  

Especially starting out, you're never going to get anywhere if you don't manage to get full and complete control if you don't have an absolute grasp on all your personal finances, if you don't know about lifestyle creep and the hedonic treadmill, if you or the person handling your money can't pinch a penny until the shield dents.4.
