7 Golden Rules When You're 30 That Will Make Life Better at 50
Ask people in their fifties what they wish they had done differently at thirty, and the answers are remarkably consistent. Few mention money first. Most mention their health, the habits they let slide while they felt invincible.
These seven golden rules sum up that hindsight. None of them is new, and none of them is a miracle. That is the point: they work because small actions add up over twenty years. (This is general information, not medical advice; your own doctor knows your situation best.)
1Do not smoke, and if you do, stop now
Smoking is the single habit most firmly linked to heart disease, many cancers and lung disease. The good news is that the body starts repairing itself soon after you stop, and the risks keep falling with every smoke-free year. Quitting at thirty avoids most of the extra risk compared with people who never smoked. If you have tried before, try again: most people who quit for good needed several attempts, and support from a doctor or a stop-smoking service roughly doubles the odds.
2Eat more real food
You cannot buy your health back later, however much you earn. Fill most of your plate with vegetables, fruit, whole grains, beans and lean protein, and treat heavily processed snacks, sugary drinks and fast food as occasional rather than daily. Cooking at home a few nights a week is one of the easiest ways to do it.
3Move every day
The World Health Organization recommends that adults get 150 to 300 minutes of moderate activity a week, such as brisk walking or cycling, plus muscle-strengthening exercise on two or more days. An active routine built at thirty is much easier to keep at fifty, and it protects the heart, bones, mood and sleep. Choose something you enjoy, because the best exercise is the one you will still be doing in ten years.
4Learn to manage stress
Meditation, breathing exercises, yoga, a long walk without your phone: the method matters less than the habit. Research suggests mindfulness practice can help reduce stress and anxiety for many people. It costs nothing but a few minutes a day.
5Travel
Travel while your knees still love stairs. See expensive hotels and one-room guesthouses, mountain peaks and city markets, on a budget and once in a while in style. New places stretch the mind, and the memories pay dividends for decades. Our list of the 20 craziest places to see before you die is a good starting point.
6Look after your teeth
Brush twice a day with fluoride toothpaste, clean between your teeth, and see a dentist regularly. Crowns, implants and root canals are expensive and time-consuming. Prevention is cheap.
7Give back
Volunteering, helping a neighbour or putting your heart into a community project is good for the soul, and studies link it to better wellbeing. Expect nothing in return but the satisfaction.
The house edge of everyday habits
There is a neat way to see why these rules matter, and it comes from the casino. A European roulette wheel has 37 pockets, but a winning single-number bet pays as if there were 36. That gives the house an edge of about 2.7% on every bet. On one spin it is invisible; players win all the time. Over hundreds of thousands of spins, it becomes a near certainty, which is why casinos can build palaces on it.
Daily habits work the same way. One cigarette, one takeaway, one skipped walk changes nothing you can see. Repeated thousands of times, a small edge, for or against you, decides the outcome. The trick at thirty is to put the edge on your side and let time do the rest. We explain the maths properly in The Science of Luck: 7 Probability Myths Busted.
The same thinking helps with money. A lottery ticket or a night at the tables can be fun, but it belongs in the entertainment budget alongside cinema tickets, never in the retirement plan.
