Communicate your vision but also your values.
Vision without values is like an aeroplane in flight without a travel compass guide. It is hazardous to say the very least and no human life is worth such sacrifice.
Sadly, at many work places, there are organizational visions and goals but very little emphasis on the values by which the vision should be accomplished.
Vision and values are inseparable pair needed for effective leadership. Communicate and serve same to those you lead because they are banking on your leadership to dictate what values and work culture are worth exchanging their lives (time) for.
