I'm a rather young father of 3 and I agree with this.

We started a family in a 31 sq m apartment, later moved into a house.

Another point is that I would not focus on finding the right one, but rather someone you think you will be compatible with long term. I've had crushes, and bad ones, and I've been in relationships where I was in love to the death. But that does not necessarily mean it works out long term. Looking at facts is better. I believe a lot of humans are compatible, and able to live together forever.

A side note is that Trace Mayer is the one who inspired me to become a dad at a young age. I hope he's doing well
