How can I become a famous doctor?

You need to get an education then work hard until you build a name for yourself.

Here’s how you do that:

Speak in absolutes. Talk in black and white. Never bring up the shades of gray because that might confuse your target audience. Words to avoid include: may, might, could, and possibly. Instead choose words like: will, won’t, always, and definitely.
Incite fear in people. Tell everyone that if they don’t follow your advice something bad will happen to you. Like inflammation or dysfunction…those are hard to disprove. Or maybe malaise, fatigue, depression, or other problems that have a hard time getting better. Then your audience will believe you, because that’s probably why they’re listening to you anyway.
Never rely on science (“evidence-based medicine”), because only your opinion (“media-based medicine” mbmed) counts. Studies with valid, patient-oriented outcomes are much harder to do and probably won’t prove your point. So why waste the time and money, when being charming and loud is much easier to make sure people know you’re right?
Never admit that you don’t know. That will just show you are a failure and you will appear less god-like to the people you are trying to reach.
