Principles are ways of successfully dealing with reality to get what you want out of life.
Ray Dalio, one of the world’s most successful investors and entrepreneurs, cites principles as his key to success.
There should always be follow-through, not interruption, unless a pressing reason exists (when, say, a person would be a great click for another job that needs to be filled immediately). In a company where things are evolving quickly and people are expected to speak openly, it is natural that there will be a steady stream of opportunities for employees to move into new roles. But if too many people jump from one job to another without fulfilling their responsibilities, the resulting discontinuity, disorder, and instability will be bad for managers, bad for the culture, and bad for the people moving, because they won't be adequately tested in their ability to move things to completion. As a guideline, a year in a job is sufficient before having conversations about a new role, although this isn't black and white--the range could easily vary depending on the circumstances.
