The don't-break-the-chain method is one of the plainest and most durable ways to build a habit. The idea fits in a sentence: for every day you do a habit, you put a mark on a calendar; after a few days those marks form a chain; and your job is simply to not break the chain. It works because it doesn't lean on motivation or willpower — both of which fluctuate. Instead it creates a concrete, visual record of progress: the growing chain becomes a reward in itself and raises the cost of breaking it. The focus shifts from a distant, abstract goal ("get in shape") to a single, repeatable action you can do every day ("add today's link"). That's also where its biggest trap lives: interpreted rigidly, a single missed day resets everything, which pushes most people to quit entirely at the first slip. Daychain was built precisely to repair that fragility — it keeps the visual power of the method while using skip and repair credits, flexible modes, and never-shaming link states so a single bad day can't erase months of progress. The goal isn't a flawless streak; it's a habit that lasts for years.
Don't Break the Chain Method
The simple consistency method where you mark every day you do a habit to build a visible chain, and your only job is to not break it.
