求翻译：3. 把职责变成优势，把自己希望做的事情变成职责，从而控制好自己的时间，这也是管理者要面对的挑战。我所研究的CEO，只有32%的人际接触是由他们主动提出的（还有5%是双方约定的）。然而，在相当大的程度上，他们似乎控制了自己的时间。促使他们这么做的原因有两个。是什么意思？

My research of CEO, only 32% of interpersonal contact is offered by them (also 5% was agreed by the parties). However, to a considerable extent, they seem to control their own time.
