Hey friend!
Are you a solopreneur?
You might have liked this post on LinkedIn last week.
I detailed my exact process of building a solopreneur operating system.
A system so effective that people started giving me kind comments:
“Now I have a content generation system that is authentic to my brand.“
“Now, there is a systematic approach that sets workflow more efficiently.“
It’s effective because it’s dead simple.
No AI agents.
No complicated workflows.
No AI tool that I’m trying to sell you.
It’s a secret feature within ChatGPT, called projects.
Combined with the powerful memory that ChatGPT has, this system had singlehandedly brought me bountiful benefits; from 26k followers to 20,000+ email leads, to an entire personalised business coach.
If you know me IRL, you’d know that I love systems that improve with you. Those that compound with you over time.
This system does that.
So go read that post!
After that, come back and read this.
For this newsletter, I’ll dive into greater detail on the 4Rs framework I taught in the carousel tutorial.
Unfortunately, many solopreneurs underutilise the critical AI memory function.
So I made it easier to remember with a 4-part framework:
1. Remember
2. Recall
3. Replace
4. Remove

1. Remember
First up - remember.
Remember is a trigger keyword you use to force a certain memory into ChatGPT’s memory database.
Oftentimes, while chatting, we don’t know exactly when ChatGPT commits our content into its memory.
Using the “remember” keyword in your prompts, you’ll trigger a piece of knowledge to be committed to the memories database.
For example:
“I’m launching a new email course to my newsletter this month. It’s going to be a 7-day course called the 7-Day LinkedIn Solopreneur Start. Remember this.”
See how it is specifically used?
You are intentionally storing a memory so it can be recalled later on.
That brings us to our next R - recall.
2. Recall
Storing information via the "remember” trigger keyword may be great, but what if you can’t recall it?
Retrieval of information passed into ChatGPT memory is as important as storage.
Here, we use the word “recall”.
The keyword “recall” is specifically used for cases where you cannot remember the details of some content you’ve spoken to ChatGPT before and want to recall it.
For example:
“I want you to write the very first email in the course. Recall everything you know about my business and incorporate it into the email.“
This way, you’ll specifically call upon ChatGPT to grab memories from its database.
But what if you want to update the memory you’ve committed?
You’ll need to replace it.
3. Replace
Memories that are stored up with the “remember” function are not fixed in stone.
They can be updated.
A trigger keyword I use is: “Replace”.
“Replace” triggers the LLM to look for the specific memory you talk about and replace it with new information.
This is equivalent to an UPDATE function in the CRUD methodology in managing Relational Database Management Systems (RDBMS).
Here’s an example:
“I will be shifting the deadline for my email course back by 1 month. Replace this with the previous deadline.“
See how “replace” could get ChatGPT to update old information?
This is critical for compounding effects in the long term. As ChatGPT memory grows and learns about you over time.
4. Remove
The last but not least of the memories is Remove.
From failed projects to invalid business ideas to unwanted information, unfortunately, sometimes solopreneurs like ourselves need to declutter our memories.
To our human brains? It’s called forget.
Removing memories using the “remove” trigger keyword is important for ChatGPT to stay sharp and relevant to the version of us today.
For this step, we can remove memories in 2 ways:
Go into ChatGPT settings → personalisation → memory → manage memories → click on the delete icon.

Use the “remove” trigger keyword in chats.
I’ll give an example of the latter:
I am going to scrap my initial plans for my email course to focus on LinkedIn growth consulting. Remove all memories related to my email course.
Why you should use the 4Rs framework
The 4R framework takes the guesswork away from using memories.
And with memories, you’ll learn with more usage that memories compound over time with more information that you feed it.
I have what seems like 100+ memories in my memories database.
With the 4Rs framework, I can open any project I’m on (health/career/business/self-improvement) and access the memories framework directly.
All without the hassle of going into settings.
I’m surprised at this point that no one is talking about this.
PS - I’ll be conducting a webinar to teach this very framework in a few weeks’ time. Are you interested? If you are, I’m offering free slots to join today. Just reply this email with “interested” and I’ll add you to the list.
Cheers and have a great week!
