Reinvent before
Reinvent before
you are forced to.
I have reinvented my career more than once: emergency physician, CEO, author, keynote speaker, and now healthcare AI. AI is changing every profession faster than any shift I have seen. The people who do well start before the change reaches them.
The five pillars of a reinvention
1
Purpose
Your "why" leads to your "what". Without it, every obstacle looks like a stop sign.
2
Plan
Anticipate the obstacles, get your house in order, and write the plan down.
3
People
Mentors, sponsors and the people you will teach next. Nobody reinvents alone.
4
Skills for the AI era
Learn the tools before they are required. Human judgment plus AI beats either alone.
5
Momentum
Take action this week, then celebrate the win. Celebration is fuel, not vanity.
