Issue #2 — The Constraint Engine
🚨 The Routine Trap
Every January, you download a habit tracker app. You set up your "ideal morning routine." You tell yourself this time will be different.
By February, you're back to chaotic mornings, feeling like a failure.
Here's why: routines ask your ADHD brain to do the one thing it struggles with — sustained, consistent behavior.
Routines are internal systems. They live in your head. They require:
- Remembering what comes next
- Deciding to start
- Willpower to continue when bored
ADHD brains have deficits in working memory, task initiation, and dopamine regulation. Routines are asking a fish to climb a tree.
KEY TAKEAWAY: Stop building systems that require you to be someone you're not. Build systems that work with your actual brain.
🛠️ Three Constraints That Actually Work
1. Time Constraints — Calendar Blocking with Teeth
Don't just "plan" to do deep work. Make it unavoidable.
Instead of: "I'll work on the product roadmap this morning"
Try this:
- Calendar block 9am-11am as "Roadmap Work — Do Not Schedule"
- Book a conference room or work from a coffee shop (harder to escape)
- Enable Focus mode that blocks distracting apps
- Tell your co-founder you'll have the roadmap draft by 11:30am
The constraint isn't the calendar block. The constraint is the social commitment + location lock + public deadline that makes quitting harder than finishing.
KEY TAKEAWAY: Time blocks alone don't work. Stack constraints so quitting requires more effort than doing the work.
2. Commitment Devices — Make Failure Expensive
A commitment device is a constraint where you pay a cost for not following through.
Example: Want to ship your landing page this week? Tell your entire email list it launches Friday. Now you have 1,000 accountability partners.
Example: Struggle with exercise? Book a personal trainer who charges if you cancel within 24 hours. Money is a powerful constraint.
Example: Can't stop doom-scrolling? Install website blockers with passwords you don't know. (Give the password to a friend.)
The principle: Increase the friction of bad behavior. Decrease the friction of good behavior.
KEY TAKEAWAY: Willpower fails. Make the wrong choice expensive, and your brain will find the right choice much more appealing.
3. Environment Design — Architecture Beats Discipline
Your environment is a constraint you set once and benefit from forever.
Marcus, founder of a $800K ARR SaaS business:
"I was constantly distracted by my phone during deep work. I'd pick it up 'just to check' and lose 45 minutes to Twitter. Hated myself for it. Couldn't stop.
Then I bought a timed kitchen safe. My phone goes in at 9am. It doesn't unlock until 12pm. No override. No escape.
First week was withdrawal-level uncomfortable. Week two, I forgot about it. Now I get 3 hours of uninterrupted work every morning without thinking about it.
The best part? I didn't build discipline. I removed the need for it."
Other environment constraints:
- Work computer has no social media bookmarks, no passwords saved for distracting sites
- Desk faces a wall (not a window with activity)
- Co-working space subscription — you're "trapped" there for the day
- Separate work phone that literally cannot download Twitter/TikTok
KEY TAKEAWAY: You can't out-discipline a badly designed environment. Change the architecture, change the behavior.
⚡ The Constraint Stack
The best constraints combine multiple types:
| Weak Constraint | Strong Constraint Stack |
|---|---|
| "I'll work on sales" | 2-hour calendar block + coffee shop with no WiFi + tell 3 prospects you'll follow up by 5pm |
| "I should exercise" | Morning class you paid for + workout partner who shows up at your door + gym clothes laid out the night before |
| "I need to write" | Public announcement of article deadline + editor waiting for draft + distraction-blocking app with no override |
Stack your constraints. One constraint is a speed bump. Three constraints is a fortress.
KEY TAKEAWAY: Don't rely on a single constraint. Layer them so you'd need to break 3+ systems to fail.
