求翻译：我认为，首先要强调的一点是，对管理者来说，对管理工作的描述，比从中衍生出的指导更为重要。也就是说，管理者对自身工作的认识，会对他们的工作效率造成显著影响。他们的工作绩效，取决于他们如何理解工作的压力和困境，又如何加以应对。是什么意思？

I think, first of all to emphasize the point is, to managers, description of the management, more important than the guidance to derive from. That is, the managers on their own understanding of the work, will have significant effects on their productivity. Their performance, depending on the pressure and difficulties of understanding how they work, how to deal with.
