Mindfulness is great because it gives us insight into ourselves in ways that go beyond the intellectual. It touches on all of these types of experience:
If much or all of your life at work has fallen into category 1, then mindfulness will feel unusual, especially at work.
You will encounter emotion. Probably much more than you did before at work. It will feel strange at first.
But it was always there. You just weren't paying attention to it. Or if you did, you paid attention when it had escalated.
Better to engage it, discuss it, and help yourself and others manage it.
A leader who helps employees and co-workers on this journey leads in this way: whole employees are happy employees are productive employees.
Understanding ourselves better makes us better at what we do.
