Similarly, as one is promoted to become a project manager or Scrum Master, thinking patterns would automatically gets adjusted to lead the team and showing attributes of a leader. Fundamenally people wait for suitable title/designation and then would try to change their thinking patterns, atleast most of the times !!
Recently, Pete Behrens one of the Agile practitioner suggested a good thought in the Agile discussion group, and thought I would share here:
If you wait for a title to behave as that title you will rarely make it
there - rather if your act and behave what you want to become,titles become
some what irrelevant.
