I kept failing at time-blocking until I realized discipline wasn't my problem, timing was...

For years, I thought I wasn't disciplined enough. I'd block my calendar, set alarms, plan the perfect morning and still fall apart by 2 PM.

The problem wasn't willpower. It was that I kept scheduling my hardest work during my biological valley without knowing it.

Once I figured out my chronotype (your body's natural energy pattern), I realised my peak focus window was 9 AM – 12 PM. I'd been wasting it on email.

So I built an app called ARC that does this automatically:

• 60-second quiz identifies your type (Lion, Bear, Wolf, or Dolphin)
• Maps your real energy peaks so you know exactly when to do deep work
• Calculates the exact time to stop coffee so it doesn't wreck tonight's sleep
• One mission at a time, no overwhelming lists, just "here's what to do right now"

The shift from "be more disciplined" to "work at the right time" changed everything for me. 3 focused hours during my peak now beats 8 scattered hours of fighting my biology.
