Why 3weeks Was Built — The Pattern Behind Resolution Failures

Why Resolutions Don't Stick
"This year, I'll exercise consistently." This kind of resolution almost never lasts. There are a few common patterns behind why.
The goal is too vague — "Consistently" has no when, how much, or how. It's hard to decide when to act, and unclear whether you did it or not.
The timeframe is too long — "For the whole year" creates psychological looseness. If not today, then tomorrow. If not this week, then next week.
Early failure leads to quitting — Missing once triggers "I've already blown it" all-or-nothing thinking.
How 3weeks Responds
3weeks addresses these patterns in three ways.
First, it guides you to define a goal as one specific, daily-executable action.
Second, the period is fixed at 21 days. Three weeks is short and concrete. "Let me just try for 3 weeks" is something people can actually say and mean.
Third, the consecutive check structure makes daily execution visible. Missing today breaks the chain, which breaks the habit of pushing things to tomorrow.
