Slow down. Life is not a race or a competition. Just because someone gets to a milestone before you means nothing to your journey.
You can do life out of order.
You do not have to have a life time career. You can choose many. You do not have to marry anyone. You can live in cohabitation with other humans or not. You do not have to have children.
The order of milestones, career, marriage, children, that society decided upon, makes sense, but it’s all imaginary. It will not work for everyone.
I dare you to jump off the schedule and live as you please. Be a free range human.
