As a doctor, I have been creating content online for more than a decade.
These are the 3 simple (but effective) pieces of advice I'd give any doctor starting out (or who wants to get started):
Advice #1: Create before you consume
From the moment we wake up we're bombarded by inputs. From the news, your social media, and podcasts you listen to. This makes it difficult to process your thoughts and form your own ideas. The solution I've found is to create before I consume.
Every morning, my phone remains in airplane mode until I produce something.
It can be an article, a few tweets, or an email I'm sending to my list. Some days it's easier than others. Some days I am done with creation in 30 minutes. Some days it takes me more than an hour. But, just like working out, I'm always glad I did it.
Advice #2: Develop a simple system to collect ideas
Once you get used to producing content, you'll begin getting ideas throughout the day.
During your commute, in conversations with your peers or patients, or while listening to a podcast. And few things are as frustrating as knowing you had a great idea a few hours prior and not being able to recall what it was when you sit down to write. The solution is to develop a simple system to create little reminders you can reference when it's time to create.
The key is to make this system as frictionless as possible so you can take a note in less than a minute and continue doing what you were doing before the idea struck.
My go-to at the time is an app on my iPhone and Mac called Drafts App.
It integrates with the shortcuts app so I can quickly take a note and send it to my Notion for reference, to ClickUp if it's a task, or even tweet it out right away. Core version is free (and more than enough for 90% of users).
Advice #3: Ship daily
You need to put in the reps.
There's no other way around it. Give yourself permission to suck at first. But don't allow yourself to skip a day. And if you do, don't ever skip two days in a row!
As long as you get your reps in daily, you'll get better.
Honestly, I wish someone had told me these 3 things earlier in my career.
But I'm at least glad I can pass them along to you.
