What's the deferent between working hard and working good?

When you work hard you give 100% of what you have and when you work good you do the 100% of what the work demands. this is the difference between working hard and working good.

Such as working without mind or with mind

The same deffernt between effictiveness and efficiancy , 

effictiviness is closed to working hard ( do things right )

efficiancy is closed to working good ( do the right things )
