I learn that I always have to think the answer of the question "What's next"?

Today I learn I'm a little manager. My boss said angrily "You can't do it at all. You onlu think the thing that is in front of you. It's not enough. You always have to think next action as a manager. From now on you never forget that you are asked all time what's next? One of your work is keeping to create new project".

In fact I was shocked his words because it means that you can't work as a manager. My plan of work was tottaly denied. But in the same time I can grow up more. The cause of this situation is lack of my skills. 

It's good study. I'll receive his indication and make use of it. The reason why is, of cource, I'm so furustrating! Never lose I am.
