The second step in the eightfold path is right thought or purpose. From a Buddhist perspective, this means keeping an eye on your spiritual goals, especially when life happens and throws you off track.
So what's the parallel to project management? The idea is to keep an eye on the big picture, and don't get bent out of shape when minor problems arise on the project. A good project manager will plan out the project in advance, but also know how to adjust the plan as the project moves forward. Change is not a bad thing; it just needs to be managed with the end goal in mind. The vision of the project should remain the same, even if some of the details change.
