Headspace counts the days you meditated in a raw using the app. It doesn’t matter how long your meditation was until you opened the program and dedicated at least 1 minute of your day to meditate.

They have special 1,2,3 minutes sessions just to keep you consistent and growing, even if it is one minute of your time. They count it.

I believe it is something similar with writing every day. Or anything else where you would like to build a consistency: just a minute of attention per day will be enough.

I will keep going. No matter how small each step will be.
