The best way to influence a leader is to find out what factors are already influencing them.
This sounds difficult on the surface, but it is not as tough as it seems. Here are some strategies:
What is their frame? How are they feeling? What factors are going on that may be influencing how they are thinking and feeling? Could these factors be making them happy, sad, depressed, etc.?
Where is their focus? What are they thinking about now? What is consuming their thoughts? Social media is a great way to determine this. What are they posting about?
What can you do to help them change (or enhance, if their focus is on good things) their frame and focus? Do you have possible solutions for their problems? Is there a way you can be there for them? Can you help them get to the next level?
Influencing a leader is about helping them with their problems and promoting their successes.
There is an old saying: “Nobody cares how much you know until they know how much you care.” -Theodore Roosevelt.
Zig Ziglar said that you can get everything you want out of life if you help enough other people get what they want.
