YOU ALREADY KNOW
WHAT TO DO
You've read the books. Downloaded the apps. Started on Monday. You have the information. You don't have the identity.
Most approaches to change focus on behaviour — what you do. The 100 Days method focuses on who you become. Because lasting change doesn't come from more willpower or better systems. It comes from the moment you stop doing a habit and start being the person who does it.
That shift happens over 100 days.
FIVE PRINCIPLES.
ONE TRANSFORMATION.
01
IDENTITY FIRST
Change starts with who you decide to be, not what you do. You don't need ten changes. You need one, done with full commitment. Focus is the strategy.
02
100-DAY BOUNDED CYCLE
A defined window changes everything. Not forever — just 100 days. The boundary creates the commitment.
03
IDENTITY, NOT WILLPOWER
Willpower is finite. Identity is permanent. The goal isn't to do the habit — it's to become someone who does.
04
DAILY OVER INTENSITY
Showing up matters more than how hard you go. Consistency is the only thing that compounds into character.
05
REPEAT THE CYCLE
When 100 days end, you begin again — with a new habit, a new goal, and a stronger version of who you are.
SIMPLE BY DESIGN.
SERIOUS BY INTENT.
The 100 Days method is deliberately uncomplicated. There is nothing to track, optimise, or gamify. You pick one habit, you commit to 100 days, and you show up.
What makes it work isn't the number. It's the decision that the number forces you to make — and keep.
That shift takes 100 days.
