After the age of 30, what money do you find unnecessary to spend?

I am in a 1.5-tier city. The summary is as follows:

1. Quit smoking and drinking if you can. It hurts your body and wastes money.

2. Don’t check social media if you can. It’s a waste of time.

3. The location of the house is the most important. It’s better to buy a house in the suburbs than a house in the suburbs. It’s better to rent a house in the city than a house in the suburbs. The location of the house determines the comfort and happiness of life.

4. Don’t buy a German car if you can buy a Japanese car. Don’t buy a turbocharged car if you can buy a self-priming car. Even if you need to accelerate, a 2-liter self-priming car is enough to step on the bottom. The quality of German cars is Benz>A>BMW. After five years, BBA will have to replace a lot of plastic parts, without exception.

5. If you are a person without perseverance like me, don’t cultivate a lot of interests. Photography, fitness, audio, fishing, everything needs investment, and everything is not cheap. Just focus on one.

6. You can buy a famous watch, just one piece, buy Rolex, Omega, Longines with low depreciation rate, and it should be a famous series. Unless you are very interested in mechanical watches, there is no need to buy PP, VC, AP, or other brands with complex functions that are in line with Rolex. I wear a 200 yuan Casio 70% of the time, and a Seiko 4 series movement can be worn for 20 years.

7. Children should cultivate their interests, but there is no need to enroll in a lot of training courses. It is good to participate in more free projects to know where the children are strong, and then specialize in one and not give up.

8. It is good to wear comfortable clothes. Quality is more important than design, unless you are very rich. Anyway, my favorite brands are three: Uniqlo, Decalon, and Clarks.

9. People's energy is limited. Even if you are a social cow, it is not easy to keep 5-7 good friends (the kind who will not doubt you when you ask for money and will lend you money immediately within their ability). Don't waste time on ineffective socializing.

10. Don't get together with slutty women. She can ruin everything for you (I have seen at least two cases around me, and neither of them ended well). When the testosterone is up, go home and have sex with your wife and you will wake up. If you think your wife is boring, that's your problem. Either train her to be a slut in front of you, or divorce her and find someone else.
