One small step at a time
Change one thing, plan when you'll do it, keep light track, and give it weeks.
Change one thing
Whether a behavior happens comes down to three things: whether you can do it, whether your day leaves room for it, and whether you want to Michie, van Stralen and West, 2011. When a change isn't sticking, ask which of the three is missing, and work on that one.
Plan the when, not just the what
"When I finish lunch, I'll walk around the block" works better than "I'll walk more" Gollwitzer and Sheeran, 2006. Every step on this site comes with a when-then line you can copy or rewrite to fit your day.
Keep light track
Writing progress down helps Michie and colleagues, 2009, more so when it's on paper or a screen and not just in your head Harkin and colleagues, 2016. A tick on a calendar is enough. Nothing here keeps a streak, and missing a day doesn't reset anything.
Give it weeks, not days
New habits took about two months on average to feel automatic, with a wide spread between people, and missing one day made little difference Lally and colleagues, 2010. If it still feels like work after a few weeks, that's normal.

Single study, 82 people over 12 weeks: one group of people; results may not repeat elsewhere.
What we use: A new daily habit took 66 days on average to feel automatic, from 18 days to a projected 254; missing one day made little difference.
