And what, from your perspective, hasn't changed at all, is very consistent with when you first started writing books?

In the book, you talk about how investors are trained to kind of delegate their thinking to their brokers.

Well, I guess in 2005, clearly like the CNBCs, and you had a lot more information than you might have had 15 years prior to that.

But do you think that that's still the case or do you think we've kind of evolved from there?

Yeah.

And, you know, kind of along those lines, you also talk a bit about activity bias, the feeling that, you know, if you're doing something, if you're, I don't want to say the word churning because it's your own account, but if you're in there actively doing something that's better than nothing, how does that hurt returns?

And do you think that that's still an issue, you know, kind of 20 years on?

Yeah.

And for a listener who is starting from zero or is very early in their, you know, kind of investing days, what's the first step you would argue for, you know, kind of building wealth?

For a listener who is maybe not a beginner, but is also not, you know, kind of 60 years old, let's, you know, let's say they're kind of in their 30s or their 40s.

How do they know if they're on track financially without, you know, kind of obsessing over the numbers, whether it's how close am I to being able to retire?

What are the metrics?

And obviously everybody's different, but just kind of broadly speaking.

What question do you wish more people asked you about money or just asked about money?

What question do you wish people were more curious about?

Well, Mark Mattson, thank you so much for the time.

Obviously, as I kind of said at the beginning, he's written a number of books that are great to read.

And there's so many other kind of mediums where you can find his work.

Mark, thank you very much for coming on Motley Fool Conversations.
