Because nobody here is willing to admit they missed the boat early on when they were young & great girls worth marriage were far more abundant. I know many couples who were high school or college sweethearts who are still together, still happy, and proud of their marriages.
This is why taking advice from this forum at your age is perilous OP. At 18 years of age yourself, and with your awareness and ambition and perspective you are in the sweet spot. If you are going to get a great wife your best window of opportunity is within the next 5 years, maybe less. Why? Because that is when the girls in your age group WORTH marrying are pairing off.
There is a red pill blogger named Ironwood you would do well to search. He is married and gives very specific advise on finding a wife as a red pill man. As far as how to find a good woman his advice is the best I've seen. I will show my high school age son (and daughter) his material when they get older.
You have all these men saying date the young girls (Duh) and old guys can out compete the men who are her peers. That is largely BS. More power to you if you are (and some here do), but let's get real. Strippers are not as a group quality women. They just aren't. Only an idiot would marry one.
Almost none of the older men here are dating the top tier women in their 20s (the 8+ women feminine girls who are either virgins or very inexperienced as measured by partner count, who come from great families and are looking to build a lifetime together with a top tier young man.). Colossus married one and Desdinova seems to be dating one as an older guy.
Colossus is a physician or physicians assistant, so he had some serious value from that standpoint and Des is a highly sought after guy as well so these men maxed out their value & found great young women.
Beautiful feminine women from great families marry young men from great families almost without exception. The families mutually support the young couple and guide them. I have new renters in one on my nicest houses. They are a young married couple, both 20 years old. The husband is in the Navy and my rent house is in a nice area and happens to be across the street from his parents. They wanted my house precisely so that the wife can be near her in-laws and with family while the husband is at sea.
I know everyone here will say marriage ends in divorce! Don't do it!...Married couples aren't REALLY happy...Don't do it! And that is true some of the time.
But it isn't true ALL the time. Many men here know people with happy marriages. Most men here would give their left nut to have a great wife in their lives.
Very few people become successful. Does that mean everyone should give up & call it good? No although many do just that.
In the same way great marriages exist. I know MANY really happy married couples. Almost all got married young to someone of similar age. But if you believe the board you'll think it's never worth it.
That is a lie. An ego protecting belief because of failures at an individual level. There are great marriages all around. We all can observe that. It's not uncommon.
Marriage is not the problem. That's silly. The problem happens when you marry the wrong person (you didn't screen properly), or you yourself have too many issues & are not prepared to be married, or a combination of those 2 things. That's it.
So a man who is considering marriage & children (who require a woman to bear & who do best in a stable 2 parent household) needs to 1. Prepare himself and 2. Choose wisely.
Why would you allow your bright future to be jaded by a bunch of people who are old & bitter & jaded to varying degrees? You are still young & life is ahead of you. Many here have regret because of mistakes they made earlier in life and the painful lessons from those mistakes greatly color the opinions here.
Do not allow the opinions of other people to sour you. You can get prepared & then choose wisely.
The advice has value to be sure, but you must also understand that you can take the advice and reap the benefit of it without buying into the whole negative attitudes and self defeating recommendations that accompany the advice in many cases.
Find some happily married men & ask them. PM Colossus.
In 20 years you'll be 38. You will have happily married friends at that point who are going through life as a team. Do you still want to be childless, spinning women endlessly and risking your health on STDs worried about knocking up randoms? Or do you want to be helping your sons or daughters prepare for high school or college & be busy building your practice and your net worth and enjoying the fruits of wise choices in your youth?
You are young & the world is at your feet. Who will you be in 20 years? In 30? In 50?
Choose wisely and be true to what YOU want, because in 20 years nobody here is going to know or care what happened to you. Maybe you can be a legend who found happiness and success. In fact there is no reason you shouldn't be. It's up to you and you alone in the end.
