The One Thing: What One Simple Question Can Do for Your Focus
Most of us don't have a motivation problem. We have a "too many good things" problem. The to-do list keeps growing, the inbox never empties, and by Friday we've been busy all week without moving anything that actually matters.

Your Life Cannot Rise Above Your Mindset: What Dr. Una Taught Me About the Real Starting Line
By Yoon Hang Kim MD There’s a question I keep coming back to — one I first heard from Dr. Nneka Unachukwu (Dr. Una), the founder of EntreMD and a physician entrepreneur who’s been teaching doctors how to build businesses since before most of us knew we needed to learn.

Five Principles of Authentic Persuasion for Physician Entrepreneurs
Inspired by Dr. Nneka Unachukwu’s (Dr. Una / EntreMD) framework on ethical selling for physicians For many physicians, the word “sales” feels uncomfortable. Medicine teaches us to diagnose, educate, counsel, and recommend. It does not necessarily teach us how to communicate the value of our work, build a business, recruit a team, develop referral relationships, or invite someone to become a client. Yet entrepreneurship requires exactly those skills. Whether you operate a priv

Doubt Isn't the Problem — Letting It Drive Is: 7 Lessons from Dr. Una on Beating Business Doubt

I recently watched a video from Dr. Una (Nneka Unachukwu, MD), founder of EntreMD, on exactly this problem: 7 Ways to Stop Doubt.
