People are Creators
When people are creating, they feel fulfillment. If a person can increase the quality, speed, quantity, or uniqueness of their creation without reducing any of those, then that person will feel increased fulfillment.
Joint creation (people creating something together) develops strong relationships among the people doing the creating. And in a very nice feedback loop, strong relationships among people empower exceptional creation.
Reality is Perceived
We can increase perceptual ability in order to understand reality more completely. In the sciences, this is done by creating tools such as telescopes. For teams, this can be done with coaching and training as well as communication tools and practices.
A team can use a common vision to align perception. Perception that is aligned can create harmonized beliefs. Harmonized beliefs allow a team to work in a united fashion.
People can choose what they perceive. For example, a person can choose the value of some work that has been created. People can also choose how they perceive change.
People disagree because they have chosen to perceive different aspects of reality.
Change is Constant
Stasis, the lack of change, is death.
Responding to change is our natural state. For example, our eye and the neurological system for sight is designed to be attracted to changes in our visual field. Our minds have the capacity to learn which is based on exposure to new experiences or ideas (and new experiences are another sort of change).
