It's true, and we can prove it is true by looking at the state of monetary affairs.

It's not like the ways to build wealth are a secret. Thousands of books have been written, millions of hours of video have been recorded, and people who are rich talk about it all the time.

But the fact of the matter is that the activities for building wealth are contrary to the normal human instincts to consume. In evolutionary terms, it made a lot of sense to get while the getting was good. Make hay while the sun shines and all that.

In money terms, that's the exact opposite of what you should do.

It is very difficult for people to overcome their instincts this way, which is why so few are successful.
