Does personal development require money?

James reads a book about personal development and decides to take his own growth more seriously. He buys a few more books, enrolls in an online course and starts attending events where he can learn from others.

Over the following months, he spends a considerable amount of money. He feels that he is investing in himself, and that makes the expense worthwhile.

One evening, he discusses this with a friend who has recently changed careers. His friend has spent very little on personal development. Most of what he has learned has come from conversations, mistakes at work, observing others and taking on responsibilities he had never faced before.

James wonders whether he has misunderstood something. He has always associated investing in himself with spending money. Yet his friend seems to have developed in ways that no course could have taught him.

He looks at the books on his shelf. Some have changed the way he thinks. Others remain largely unread.

He begins to wonder what, exactly, he has been investing in.
