The One Book That Changed How I Lead (Hint: It's Not What You Think)

When people ask me for leadership book recommendations, they expect the usual titles.

But the one that changed how I lead?

Team of Rivals by Doris Kearns Goodwin.

This biography of Abraham Lincoln taught me more about leadership than any business bestseller.

Why? Because Lincoln didn’t surround himself with people who always agreed with him.

He intentionally built a team that challenged his thinking. Called him out. Pushed him to grow.

That’s what real leadership looks like.

Here’s what the book taught me:

• You are who you’re around

• You mirror the people near you

• Your advice is only as good as its source

If your circle is small, stagnant, or afraid to be honest with you—so is your leadership.

Since reading this book, I’ve become ruthless about who I let influence me.

I ask: Where is this advice coming from?

Am I being challenged or just validated?

Because great leaders aren't always right.

But they do build teams that won't let them be wrong.

If you want to grow as a leader, start by auditing your inner circle.

Because your circle shapes your ceiling.

And your ceiling determines your success.
