Key Takeaways
- Psychologists call it the “fresh start effect”: we’re measurably more likely to pursue goals right after a temporal landmark, and September is one of the strongest landmarks most adults have.
- The motivational boost from a fresh start typically lasts only a couple of weeks, so pairing it with real structure matters.
- Goals framed as “start doing X” tend to outperform “stop doing Y” goals over the long run.
September works on your brain the same way New Year’s Day does, and for many adults, even more strongly. Psychologists call this the “fresh start effect,” and it’s backed by real behavioral research, not just a marketing trick around back-to-school season. Here’s why this particular month is genuinely a smart time to start something new, and what to do so the motivation doesn’t fizzle out by week three.
The fresh start effect, explained
Researchers Hengchen Dai, Katherine Milkman and Jason Riis, in a widely cited 2014 study, found that people are significantly more likely to pursue their goals right after what they call “temporal landmarks”, moments like birthdays, new months, or holidays that psychologically separate the past from a fresh chapter. As Psychology Today describes it, we tend to act on good intentions far more successfully when we attach them to one of these marked moments, rather than trying to start on a random, arbitrary date.
Tip: If you’ve been meaning to start something for weeks, don’t wait for “the right moment” to feel obvious. Attaching your start to an actual date on the calendar, like the first of the month, measurably improves your odds of following through.
Why September hits differently than January
For most adults, September carries a specific kind of psychological weight that January doesn’t. As Inc. puts it, most of us spent well over a decade of our lives treating September as the moment to buckle down and build toward something, long before January resolutions ever entered the picture. That association doesn’t disappear once school ends, it just quietly resurfaces every year around this time, layered with cooler weather and a more structured routine after the looser pace of summer.
The window is real, but it’s short
Here’s the catch: the fresh start effect opens a motivational window, it doesn’t keep it open indefinitely. One analysis of the research, from Roon, notes that the boost tends to provide something like two weeks of elevated motivation, while actually forming a new habit takes considerably longer, an average of 66 days according to widely cited habit-formation research.
Tip: Use the first two weeks of heightened motivation to build the routine itself, the specific days, times, and structure, rather than relying on that same burst of energy to carry you all the way through.
Set an approach goal, not an avoidance goal
Research covered by Inc. distinguishes between “avoidance goals” (stopping or preventing something, like “stop skipping workouts”) and “approach goals” (starting something new, like “practice yoga three mornings a week”). Approach-oriented goals tend to hold up better over time, likely because they give you something concrete to do rather than just something to resist.
“I’ll get back into shape” is vague enough to quietly dissolve by October. “I’ll show up to a live 6am class three times a week starting September 16th” is specific enough to actually stick to.
Why structure matters more than motivation
Since the fresh start effect’s energy fades within a couple of weeks, what carries a new habit through to the 66-day mark and beyond is structure, not willpower. A program with a fixed start date, a scheduled cohort, and a defined end point, like BENDY’s live sessions running from September 16th to October 5th, gives the fresh start effect somewhere concrete to land, rather than asking your motivation alone to survive the full stretch.
If you’ve been meaning to deepen your practice, this September genuinely is a good window, not because of anything mystical about the month, but because your brain is measurably more receptive to starting right now than it will be in a random week in November.
“Every September, I see the same thing: people show up with more resolve than they had all summer. It’s not a coincidence, it’s just how our minds are wired around new beginnings. The trick is giving that resolve somewhere real to go.”

Frequently Asked Questions
Is the fresh start effect just for January resolutions?
No, research shows it applies to any meaningful temporal landmark, including birthdays, new months, and the start of a new season, not just January 1st.
Why does September specifically feel like a fresh start for adults?
Many adults associate September with over a decade of back-to-school routines, which appears to leave a lasting psychological link between this month and starting something new.
How long does the motivation from a fresh start actually last?
Research suggests the elevated motivation typically lasts about two weeks, which is why pairing it with a structured plan matters more than relying on momentum alone.
Should my new goal be about starting something or stopping something?
Research suggests approach goals, adopting a new behavior, tend to hold up better over the long run than avoidance goals focused on stopping something.
What if I miss a session once I start?
Habit research suggests missing a single day doesn’t meaningfully derail habit formation, it’s abandoning the habit altogether that does the damage, so one missed class isn’t a reason to give up.
Whatever you’ve been meaning to start, September is genuinely one of the better windows to actually do it. Just make sure the structure you build is strong enough to outlast the initial motivational spark.
