Consistency
The one that actually determines whether any of the rest matters.
The pillar that decides the rest
This is the pillar that decides whether any of the others matter. The best program on paper does nothing if it doesn't get followed, and a mediocre program followed for months will outperform a perfect one abandoned after two weeks.
Systems, not motivation
Consistency isn't about motivation. It's about building a routine specific enough that showing up doesn't require a decision every time. That's most of what tracking is for: not to create pressure, but to make progress visible enough that continuing feels obvious.
Habits over heroics
Small, repeatable habits beat occasional heroics.
Six months, not three weeks
A realistic schedule you can maintain beats an ambitious one you abandon.
Make it visible
Progress you can see is what makes continuing feel obvious.
