What advice do you have for children from humble backgrounds?

Eat well, or you'll age quickly.
Pay attention to pedestrians on the street, and you'll notice many have "carbohydrate faces, inflammation faces," rough, greasy, dull, with large pores.
Let's put it this way: if a carbohydrate face appears before you get rich, your face will be set for life. This is no joke.
Observe the dietary habits of ordinary people, and you'll find a common pattern: high sugar, high oil, high carbs, with almost no concept of "anti-inflammatory" foods.
Breakfast is fried dough sticks, buns, soy milk with sugar; lunch and dinner are mainly refined rice and noodles, paired with stir-fried dishes cooked in hot oil; snacks are cheap puffed foods, soda, milk tea.
This way of eating is fine when you're young, but by the age of 25 or 30, you'll start to notice yourself becoming more "vulnerable."
Easily insomnia at night, sleepy during the day, tired no matter how long you sleep, with scattered attention. You might think it's "life stress," but a large part of the reason is that your body is in a chronic inflammatory state.
Many people have only a superficial understanding of this concept. Here's a simple science explanation: the high oil, high sugar, high carb foods you eat produce a lot of waste. The body is very smart and will automatically clear this waste, and this process is inflammation.
This in itself isn't a problem, but if you eat like this every day, the system will overwork and wear out. First, collagen loss occurs, and your appearance visibly declines. Then, your overall vitality and spirit start to "collapse."
And the point at which you "collapse" coincides with a critical period in your life development.
Modern scientific research shows that the human brain only fully develops after age 30, meaning your cognitive and judgment abilities peak after 30. This aligns with statistics on wealthy lists: according to Hurun, most unicorn founders start their businesses after age 35.
But the problem is, many people's energy can't sustain until that stage. Most people experience a sharp decline in energy after 30.
Cognition improves, but energy can't keep up. For the poor, this is a hidden trap that makes you accept the fatalism of "this is just how middle age is."
However, if you have basic healthy eating habits, you can avoid this trap. Even if your energy has already declined, you can recover to some extent.
This isn't about strictly following so-called "anti-inflammatory diets," which are costly and unaffordable for most workers, and also take away a lot of life's pleasures.
What truly matters is that you value the impact of diet on your health. You need to understand that everything you eat becomes part of you. You can't just eat whatever you want, whenever you want; you need to manage your diet like running a business.
Try to avoid fried foods and high-sugar foods;
Don't eat only refined rice and noodles—include whole grains and coarse grains;
Ensure sufficient vitamins and proteins;
Watch your weight and avoid excess; engage in some exercise appropriately.
As long as you stick to these, your physical health can surpass most people.
And these are things that can be maintained through persistence, with very clear cause-and-effect relationships, unlike wealth, status, love, or luck factors. If you can't even ensure sufficient vitamins, there's little hope for other aspects.
