“一个人，你在不同时间段里面你的单位时间价值是不一样的。” “A person’s hourly value changes depending on the time of day.”

When you first started working, your hour was worth $100. That means accompanying your girlfriend to chat has an hourly rigid cost of $100 as well.

Later, as your value rose, your hour became worth $1,000. Unfortunately, that rigid cost of chatting with your girlfriend also climbs to $1,000. From an economics perspective, is it more cost-effective to find a partner when your time is worth $100 or when it's worth $1,000?

Go back even further to your college days. Your hour was worth pennies—almost nothing. Finding a partner then was essentially zero cost.

No matter how long you endure at work, you can't spend your life with the company. Eventually, you'll be shown the door, because opportunities always need to make room for younger people.

So, the key is to move faster than everyone else, starting while your time is still cheap—not dragging things out until your time becomes expensive. That's how you keep a good rhythm in life.
