XP TRACKERThe best habits to build in your 20s
Your 20s are when many of your adult defaults get set: how you sleep, spend, eat, move and keep in touch. You don't need to build all of them at once. Pick the one or two that would make the biggest difference to your week, start them small, and add more as they settle.
Short answer: The habits most worth building in your 20s are the ones that compound: a regular sleep schedule, moving most days, cooking simple meals, saving part of every pay, reading, and keeping in touch with friends. Start with one or two, keep each to a small daily version (10 minutes, one meal, one message), and add the next one once the first runs without a fight.
Why your 20s are a good time to build habits
A lot changes in your 20s: you leave home, start work, move cities, change jobs. Each change breaks up old cues, which makes it a good moment to set new ones. Bas Verplanken and Wendy Wood (2006) described life changes like moving as windows when old habits loosen and new ones are easier to start.
The other reason is time. A daily habit repeated from 25 to 35 is about 3,650 repetitions. Ten minutes of reading a day is over 600 hours across that decade. You can work out your own numbers with the habit time calculator.
Ten habits worth building, with a starter version
- A regular sleep time.Adults generally need 7 or more hours. Pick a lights-out time you can keep on most weeknights and protect it. Starter: phone on the charger outside the bedroom 30 minutes before that time.
- Move your body most days.You choose the form: gym, running, football, dancing, long walks. Starter: 10 minutes after work, three days a week. If you've been inactive for a long time or have a health condition, check with a doctor before a hard programme.
- Cook a few simple meals.Knowing five dishes you can make tired saves money and helps you eat better. Starter: cook at home two weeknights, the same easy dish is fine.
- Pay yourself first.Set up an automatic transfer into savings on payday, even a small percentage of each pay. Starter: look at your bank balance once a week, every Sunday. Our pages don't give financial advice, so for bigger decisions talk to a qualified adviser.
- Keep in touch with friends.Friendships made at school and university often fade when nobody makes plans. Starter: message one friend a day, and make one plan a month.
- Read.Books, long articles, anything that holds your attention for more than a minute. Starter: 10 pages before bed. See how to read more books.
- Plan your day.Two minutes in the morning to write the three things that matter today. It keeps work and life admin from swallowing each other.
- Look after your teeth and skin.Boring and worth it. Starter: floss after brushing at night; sunscreen next to your toothbrush in the morning.
- Learn one skill on purpose.A language, an instrument, coding, drawing. Starter: 10 minutes a day, same time. Progress over a year surprises most people.
- A weekly reset.Laundry, a quick clean, a look at next week. Starter: 30 minutes on Sunday. A weekly reset checklist helps you plan it.
Where to start, by situation
You don't need all ten. Start where the pain is. This table suggests a first habit for common situations in your 20s.
| Your situation | Start with | Starter version | Add next |
|---|---|---|---|
| Always tired | Regular sleep time | Phone out of the bedroom 30 min before bed | Morning walk |
| First job, money is tight | Weekly money check | Sunday balance check, 5 minutes | Cooking two nights a week |
| Just moved, few friends nearby | Keep in touch | One message a day | One class or club a week |
| Living alone for the first time | Weekly reset | 30 minutes on Sunday | Cooking at home |
| Feel stuck in a job | Learn one skill | 10 minutes a day | Daily planning |
| Out of shape after university | Move most days | 10 minutes, three days a week | Regular sleep time |
If you're starting your first job, the first job habits page goes into that week in more detail.
An example first month
- Week 1. One habit only. Pick the cue: "When I get home from work, I change and walk for 10 minutes." Mark each day on a calendar.
- Week 2. Same habit. Write down what you'll do on the nights you're out late: 2 minutes of stretching instead.
- Week 3. If the walk now happens without much debate, add a second habit with its own cue, such as cooking on Mondays and Thursdays.
- Week 4. Look back. Count the marks. Keep what's working, shrink what isn't, and leave the rest of the list for next month.
In the best-known study, new daily habits took a median of 66 days to feel automatic (Lally and colleagues, 2010), so a month is a start, not a finish.
Common mistakes
- Copying a stranger's perfect routine. A 5 a.m. start and an ice bath work for some people. Build around your job, your sleep and the people you live with.
- Starting all ten in January. Each new habit needs attention in its first weeks. Two at once is plenty.
- Waiting until life settles down. In your 20s it rarely does. Tie habits to cues that survive moves and job changes: waking up, meals, getting home.
- Treating a missed week as the end. Late nights and travel happen. Come back the next day with the small version. The get back on track guide helps after a longer break.
- Choosing habits to look good. A habit you picked for someone else's approval is the first one you'll drop. Choose the ones you'd keep if nobody knew.
What the research says, carefully
No study has ranked the "best" habits for people in their 20s, so treat any list, this one included, as a menu. What the research does support is how to build whichever ones you pick. Lally and colleagues (2010) found that adults formed a new daily habit in 18 to 254 days, with a median of 66, and that simpler behaviours settled faster than harder ones. Gollwitzer and Sheeran (2006) reviewed 94 studies and found that if-then plans ("If it's 19:00 and I'm home, I'll cook") had a medium-to-large effect on people reaching their goals. Small, specific and tied to a cue is the pattern that keeps coming up.
What to do today
Read the list again and pick one habit, the one that would make next week easier. Write its starter version and its cue on a sticky note, put it where you'll see it tonight, and do it once before you go to sleep.
A paper calendar is a fine way to keep count. XP Tracker turns these into daily quests instead: core quests such as Physical Training, Daily Reading and Plan Your Day, plus add-ons you pick like Cook at home and Message a friend, and each one you finish earns XP toward your hero's next level.

Questions people ask
What habits should I start at 20?
Start with the ones that support everything else: a regular sleep time, moving your body most days, cooking a few simple meals and a basic money habit such as moving some of each pay into savings. Pick one or two, not all ten.
What is the most important habit to build in your 20s?
It depends on your life. For many people, a steady sleep schedule makes the rest easier, because energy and mood shape every other habit. If your sleep is fine, look at the area that causes you the most stress right now, often money, health or friendships.
How do I build habits in my 20s when my schedule keeps changing?
Tie habits to events that happen every day, such as waking up, the first coffee or getting home, rather than to clock times. Keep a two-minute version for chaotic days, so a shift change or a late night doesn't end the habit.
Is it too late to build good habits at 29?
No. Adults form habits at any age through steady repetition. See can you change habits as an adult for what changes with age and what stays the same.
What bad habits should I stop in my 20s?
Common ones people regret are late-night scrolling that eats into sleep, spending without looking at their balance, skipping meals and replacing them with takeaway, and letting friendships fade by never making plans. Replace them with a small opposite habit rather than trying to quit by force.
