🧠 Intro: I’m Not Special, I’m Just Wired Differently
I’m not special. I don’t have elite willpower, I have the same 24 hours you do. I don’t have a six-figure mentor, or access to some private productivity Discord full of life-hacking billionaires. (I do have a discord though, and you should join it!)
What I do have is ADHD and a strong desire not to rot slowly in a chair while scrolling Reddit wondering why nothing’s changing.
⚙️ ICNU: The ADHD Cheat Code You’ve Never Heard Of
Ever heard of ICNU? Yeah, me neither—until I got ambushed by it on a podcast interview. It stands for Interest, (reasonable) Challenge, Novelty, and Urgency.
If a task doesn’t hit at least one of those, my brain files it under: “We’ll die before doing that.”
Laundry? Doesn’t stand a chance. Dishes… Nope. At least not until 10 minutes before someone is coming over because the urgency is now there. It explains a lot of procrastination in my life.
But what about video games? Now those hit all 4 criteria, I can sit and focus on those for hours – leading you to think I might not have a focus problem. The reason is ICNU.
🧪 How I Hacked My Own Brain
Learning about ICNU was like finding out the user manual for my brain had been taped under the desk the whole time.
Suddenly I wasn’t lazy or undisciplined—I just needed tasks to hit the right neurochemical switches.
100 day challenges are short enough to trigger the novelty, long enough to be challenging, produce a sense of daily urgency due to public accountability, and novelty due to the new nature of the challenge. This makes 100 day challenges oddly perfect for my brain and likely yours too.
📈 Why 100 > Resolutions
Resolutions are cute. Like “I’m gonna drink more water this year” kind of cute. They’re vague. Optional. Built to fail by February.
100-day challenges? They’re measurable, time-boxed, and public.
That’s not a dream—that’s a system with teeth.
Why 100-day challenges work better:
- Defined start and end
- Public accountability
- Daily structure and repetition
- Built-in urgency (especially around day 70 when you want to quit)
- Quantifiable progress
- Built-in reflection at the end
💥 The First Time It Worked: #100DaysOfCode
In 2021, I did my first #100DaysOfCode. Then another. Then another. Then another. I basically ran a 400-day dev sprint with my brain held together by dopamine, stubbornness, and sarcasm.
The result? I went from making $49,000 to over $300,000 in just 3 years.
Just from showing up and tweeting every day. No gatekeeping. No secret sauce.

🧨 Why I’m Hooked Now
I don’t do moderation. I don’t have a middle gear. 100-day challenges let me channel the chaos into something productive.
It’s like turning your brain’s glitchy wiring into a feature.
And let’s be honest—failing publicly is way more motivating than failing privately. You either improve… or get roasted. Win-win.
📣 Call to Action
If you’ve ever felt stuck, undisciplined, or like your goals evaporate faster than your attention span—try it. Pick a challenge from the list that matters. Declare it publicly. Show up every day for 100 days. Tell me about it because I want to follow your journey – I think its cool as hell!
You might not become a millionaire… But you’ll become someone who follows through. And that’s rarer than money.

Despite wrestling with ADHD, anxiety, and an unrelenting need to optimize everything, he transformed his career and life in just a few years—not because he’s special, but because he figured out how to turn obsession into execution. Now, he’s doing it again—publicly—one 100-day challenge at a time.
His past projects? Some were successes. Some flopped spectacularly. Each one left him a little wiser (and probably a little more caffeinated). Now, he’s on a mission to document his transformation—mind, body, career, and everything in between—so that others might pick up a thing or two along the way. Or at the very least, be entertained by the chaos.
