My advice to young men: marry a good woman. You won’t regret it.

Very good advice. Nothing like a good woman. Even better if she looks good and can cook. You might as well have won the lottery. 🙂

“By all means marry; if you get a good wife, you’ll become happy; if you get a bad one, you’ll become a philosopher.”

— Socrates (philosopher)

What one sees before marriage is not a true reflection of anyone’s personality. You can barely get to know the other person & vice versa. So, Keep first 6 months post marriage as trial period. It will be good for both. You will know a lot, though still not all, About the other person which would help you in ascertaining if you both are right for each other.
For myself I feel that all marriages should have an expiry life which should be renewable.

Define "good". I think we'd all have different nuances of what that means to us.

How to identify a woman is good?

It’s a good advice and same goes for young women too.

I did. I found her early and didn't let her escape.

That's good advice.

I agree
