Why productive is so difficult to get common understanding?

How do you recognize a football player is a very good player?

A person that himself or helping the team make goal?

I agree only 50% of this, for me, a good player is a person that himself or helping the team make goal to the OPPONENT, if he so happen kick the ball into his own's gate, NOT only he doesn't make a goal, he actually make the team have to work twice to get the score back, 1 to balance it, 1 to really make it to 1-0!!

Then how do you judge a person is productive or not?

Deliver the work is consider productive?

Again, I only agree if this person delivery the RIGHT product, else, he is just pulling and wasting everybody effort.

Why there are people that NEVER get understand this.
When you tell we need to find a way to be more productive, then he told he make the thing work, and NEVER EVER recognize that making the RIGHT product is the key??

Don't complain why the work being done is never get appreciate, this world is crucial, find a way that can work with the real world is the way to survive good.
