Week 4 · Lesson
Your 90-Day Plan
Four weeks ago, you didn't know how a large language model worked. You probably weren't sure when to trust AI output. You might have been copying and pasting mediocre prompts and wondering what the fuss was about.
Look at where you are now.
You understand the mechanism. You know the strengths and the failure modes. You can write prompts that get genuinely useful output. You've used AI for writing, analysis, decision-making, and meeting prep. You've built a custom tool.
That puts you ahead of the vast majority of working professionals. And I'm not saying that to make you feel good. I'm saying it because the gap between people who can use AI effectively and people who can't is growing every single week.
But here's the thing: a course is just a starting line. What you do in the next 90 days determines whether this sticks or fades.
Three habits that separate AI users from AI power users
Habit 1: Default to AI first.
Before you start any task, take three seconds and ask: could AI do the first 80% of this? If yes, start there. If no, do it yourself.
The habit isn't about using AI for everything. It's about checking. That three-second pause, over time, rewires how you approach work. You stop seeing AI as a separate tool and start seeing it as the starting point.
Habit 2: Iterate, don't accept.
The first output from AI is almost never the final product. It's a starting point. Push back. Say "make it shorter." Say "that's too generic, here's what I actually need." Say "argue against this."
The people who get mediocre results from AI are the ones who take the first answer. The people who get great results treat AI like a collaborator, not a vending machine.
Habit 3: Try something new every week.
You covered this yesterday, but it bears repeating because it's the habit that keeps you from plateauing. One new tool, one new feature, one new use case. Every week. It takes 10 minutes. The compound effect over 90 days is enormous.
Your 30/60/90 day milestones
By Day 30: AI should be part of your daily routine. You should have two or three workflows where you use it without thinking about it. Writing, meeting prep, analysis. Whatever fits your work. The goal is that using AI feels as natural as using email.
By Day 60: You should have at least one custom tool (a Custom GPT or Claude Project) that you use weekly. You should be able to look at a new task and immediately know whether AI will help and which tool to use. Other people should start noticing you're faster.
By Day 90: You should be the person on your team who others come to with AI questions. Not because you're a tech expert, but because you've been practicing. You should have strong opinions about which tools work for what. And you should be able to teach someone else the basics in 15 minutes.
The gap is real
Every week you practice, you pull further ahead. Every week someone else waits, they fall further behind. This isn't a subtle shift. This is a fundamental change in how knowledge work gets done.
You now have something most people don't: a foundation and a plan. Use it.
Tomorrow is our final lab. We're going to build something real, write your personal AI strategy, and close this thing out. Show up ready to work.
This course gave you the foundation. The next 90 days determine whether it sticks.
