In her recently published book, Pivot Points, Julia Tang Peters identifies five decisions every successful leader must make:

1. The launching decision makes a commitment to mater specialized skills in order to no more, much more than the given job requires.

2. The turning point decision responds effectively to an important opportunity or problem that usually requires a bold, neew direction.

3. The tipping point decision, involving significant risk, breaks through a fundamental, well-entrenched barrier.

4. The recommitment decision focused on purpose-driven leadership and sharpens the vision, moving the goalposts further out.

5. The letting go decision facilitates new sustainable leadership.

All of this is thoroughly discussed in Pivot Points: Five Decisions Every Successful Leader Must Make, published by John Wiley & Sons (2014).
