Get away. Change activities. Change pace. Taking a long weekend or holiday is a good capacity building strategy for those who want to be at their best. Effective people know that making a change relaxes and increases a sense of well-being. This creates a climate where new insights can pop into your mind. That fresh thinking can be important to the very project you were working on.
Renewal is not slacking and laziness. It is good management of your most important resource … you.
