If you do something ten days straight but drop the ball on day 11, restarting will feel especially hard. But I believe this only to be the case when I decided not to show up. When I could've done it but made an excuse. Whenever I've taken a day off because life happened, I found it just as easy to pick up the following day, or at the most the following week.

What is life happening though? If there's a day when I don't write -- hasn't been for awhile now, but i spent many days not writing in the last decade -- besides for maybe 20 total days, I always chose not to write. On those 20 or so days I had something special going on. Life. And I chose to do something other than write because it was worth it.

But most days are ordinary. And most days I just chose not to show up.

I think if you're trying to develop a habit, then first you got to know why. Otherwise, you'll start choosing other things and calling that 

life happening
