PS: I don't mean to offend anyone. I only want to share my personal experience.
Female cousin: She's now in her late 20s and looking to settle down. However, ever since she was 18, she's had tons of boyfriends, did tons of parties; I celebrated that she got to enjoy her 'party years." No judgment on my part.
Male cousin: My cousin was unattractive throughout high school and college. He stayed in his dorm playing video games while everyone was partying. Now that he is in his late 20s. He has a small business(location independent), bought a condo(doesn't have to worry about rent, inherited some money from some family, had savings), and plans to rent his condo to make a side income. He told me he wants to spend his 30s traveling to Europe, hooking up with women, and going to nightclubs and concerts. We were learning French and German together. He met a professional woman; she was a straight gal, not a party type, and saw her for a few months before breaking it off. She wanted to be more serious, but he didn't want to.
Who am I tell my cousin, 'No, don't do it? You should settle down!' My cousin is a guy who I feel needs to enjoy his life!
Acquaintance: I have an acquaintance who got married in his late 20s and has a kid. He's now in his mid-late 30s. His marriage ended up in divorce after 6-7 years. It did not end 'acrimonious' instead; it ended up amicable**. However, once children are in the picture, priorities change. My acquaintance has to work even harder to support his child.** I highly doubt that he can use that money for himself, to have fun.
These are just some thoughts I feel for some people there's a narrow way life should be like. But my view is that people should do their own thing.
