Three tools so you stop planning by eye
Each one answers a single question, and answers it with numbers. They come with an example filled in: you see them working before you touch anything.
Does your day fit?
Add up what you want to do today and it tells you how many hours you are short. Almost no plan collapses for lack of willingness: it collapses because it never fitted.
Work out my dayHow long does it take to form a habit?
Not 21 days: that number comes from a 1960 book on plastic surgery. The study that actually measured it found 66 on average and a range from 18 to 254. This gives you your own band.
See my rangeWhich habit should I start?
A weighted decision matrix: enter your candidates, the criteria that genuinely matter to you and how much each one weighs. It returns a winner, the margin and the criterion that decided it.
Build the matrixWhy these are here
Monkway is a habit app. These three tools settle the three decisions that come before you open any app at all: whether the day fits, how long you will have to keep going, and which of all the habits you want to start goes first.
They run in the browser, store nothing and ask for no email. If by the end you want something to count the days for you, that is what the app is for.
What they do not do
They do not email you a PDF in exchange for your address. They do not score your life. They do not decide for you: they put the numbers in front of you so you can decide.
Where the data comes from
The 66 days come from Lally et al. (2010), How are habits formed, European Journal of Social Psychology. So does the 18-to-254 range. It is cited inside the tool itself.
You have the numbers. Now it has to be done
Monkway counts the days you have kept it up, reminds you when it is time, and keeps the habit on file for the days you forget why you started it.
