Effective leaders plan for the future, including for a time when others will step into their roles. Leaders can learn a lot about succession planning from Yoda, the fictional but wise Grand Master of the Jedi Order in Star Wars.
Yoda trained many young Jedi, including Luke Skywalker. Building the next generation of leadership in your company is also a must to ensure a smooth succession when you retire or if you should become incapacitated or die. The same is true for key staff members.
