When a man becomes a father, his salary often increases. When a woman becomes a mother, hers often decreases. This is not anecdotal. It is a well-documented economic phenomenon known as the motherhood penalty. Over time, it can cost women hundreds of thousands of dollars in lost income, missed opportunities, and reduced long-term wealth.

The biggest wealth-building mistake most women make is waiting. Waiting until they earn more. Waiting until the debt is gone. Waiting until they understand it better. Waiting until they feel ready. The problem is that waiting has a cost. And that cost is paid in compounding returns you will never get back.
