Not everyone considers it a sacrifice to not be married or have kids. For the people who do fewer than half of them are happy that way.

We're all pretty bad at knowing what will make us happy in advance.

I'm not exactly saying not having a family is a sacrifice, but where you want to live. The cheapest apartment I could find in my area (before kids/marriage) was about $700 and that's a few cities away in a no-so-great area where cops were getting called to our neighbors every few days. I could go closer to downtown and be in a worse area.

With kids, the cheaper areas have generally worse schools, parks, etc.
