This is the main point here, IMO. A child is a huge responsibility and the early 20s is a period of life you're still figuring things out. Culture also plays a role here; where I'm from, people are deciding to live together (without having kids) for a couple of years before formally marrying.
Even if one has phased it doesn't mean the centering will have aligned to the perspective of the right vibration intensity, obviously alluding to the fact that the crossing of the horizon of one's self is not independent to the will of the resonance
I love NakeyJakey, Sage Rain, ThorHighHeels, and Jacob Geller. They mainly talk about games and stories with a few random videos here and there and they do an excellent job at making hours-long entertaining videos with lots of passion for the topics they cover.
