So too frugal, by the way, I was too frugal, but it did put me in a position to learn discipline.

I've never spent earned income to improve my standard of living.

So earned income, if I make $100,000 and I have $40,000 left over, the whole $40,000 gets stored.

So when my friends were all buying a Rolex or a BMW or going on vacation, I wasn't like nobody knew I was rich until I was about 45 years old.

Anything extra, I store that to invest.

I can only buy a Rolex when I have passive income.

People like, hey, what are you doing?

I never, ever rented a private plane.

I can only buy a BMW when I have passive income.

I've never been on a private plane until I bought my own plane.

So I have these little rules that I put in on myself that I believed if I would use these rules, they would make me wealthy one day.

But this is years, 25 years of me making investments.

I wasn't saving money.

I mean, I was being frugal to some degree, just because I personally would never spend earned income.

I just didn't know how wealthy.

I had no idea, to be honest with you.

But I was so disciplined.

I have great work ethic.

That's one thing I have that nobody can take away from me.

This is something that will, if you use this one principle, you are guaranteed to be rich.
