Good Leader, Bad Leader

A field guide to the people, power dynamics, and leadership patterns that shape your career.

20 real leaders. 20 recognizable patterns. One uncomfortable question: which one are you?

You will recognize your best boss, your worst boss — and possibly yourself. More importantly, you will learn how exceptional leaders read people, navigate power, make difficult decisions, build trust, and lead under pressure when it matters most.

What if your biggest career lesson comes not from success — but from poor leadership?

After more than 18 years in the corporate world, Vladimir Greavu draws an honest conclusion: leadership determines success, motivation, and often the next step in your career. In Good Leader, Bad Leader, he analyzes 20 real-life leaders who shaped his path — from the inspiring to the destructive — and combines personal experiences with clear, practical lessons for modern leadership.
