Green: getting better every day. Brown: getting worse every day. The gap between the two lines is the whole argument for showing up daily.
The math behind the meme
The "1% better every day" idea was popularized by James Clear's Atomic Habits: improving by just 1% daily means you're 1.01365 ≈ 37.8 times better after a year, while declining 1% daily leaves you at 0.99365 ≈ 0.03 — near zero. The point isn't the literal number (life isn't compound interest), it's that consistency beats intensity: small actions repeated daily dominate occasional heroic efforts.
The hard part was never understanding the math. It's showing up on day 43 when nothing visible has changed yet — that's exactly the flat part of the curve above, and it's where most people quit.
