03How to pick a challenge you'll finish

• Choose one. Two challenges at once usually means neither gets finished.
• Make the daily task small. If you can't do it on a tired evening, shrink it.
• Attach it to something you already do: after coffee, before bed, when you get home.
• Decide now what a missed day means. The gentlest rule that still works: never miss two in a row.

04How to choose the right challenge for you

The best challenge is the one you finish. Three questions narrow it down quickly:

1. Add or remove? Adding something (“walk daily”) is easier to start. Removing something (“no sugar”) is harder but often changes more.
2. How long does it take each day? Under ten minutes is easy to protect. Over thirty needs a fixed slot in your day.
3. Can you do it on a bad day? If illness, travel or a late night would break it, make it smaller.

0530-day challenges by month

Some challenges fit the calendar. If you like a theme, here is one for each month.

06A four-week plan that works for any challenge

• Week 1: make it easy. Do the smallest version. The aim is seven ticks, not seven impressive days.
• Week 2: fix the time. Attach it to something you already do, such as after coffee or before bed.
• Week 3: expect the dip. Motivation drops around here. Look at the row of ticks behind you; that is the reason to keep going.
• Week 4: decide what stays. On day 30, choose: keep it, shrink it to a maintenance version, or let it go.

07What happens after day 30?

Thirty days gives a habit a strong start, but it rarely makes it automatic. The best-known study on habit formation found an average of about 66 days, with a wide range. The practical lesson: if the challenge is worth keeping, carry on for another month. We explain the research in how many days it takes to build a habit.

08Doing a challenge with someone else

Doing it with someone gives you a second reason not to quit. It works best when you keep it light:

• Agree on the same start date and the same definition of “done”.
• Send each other one message a day: a tick, a photo, a single word.
• Print one sheet each and compare on day 15 and day 30.

09How we made this

We build Habbles, a habit tracker with 25 built-in challenges. The ideas on this page come from the challenges and habit templates in the app, plus the ones people most often search for. Each is written so that “done” is obvious at the end of the day.
