So you can get junk sleep and a lot of people do that.

So high quality sleep is completely different.

And I know this because I was the guy who got five minutes of deep sleep every night and five minutes of REM sleep

in eight hours.

So I was asleep.

I was not conscious, but nothing good was going on.

So I've been tracking my sleep just about every night for 20 years, and I learned how to get really good deep sleep.

And I've taught hundreds of thousands of people how to do it.

It's free.

Go to sleepwithdave.com, which is the best URL of my entire marketing life because it's funny.

But you go there, and this is all the stuff that works.

But number one,

The part of your brain that tells your body whether to go into sleep mode is called the SCN.

And the number one thing that controls it is the color and the brightness of light.

So we have these LED lights in the bathroom, in the kitchen, and it takes two seconds of exposure to tell some parts of your brain, oh, bright light that's never existed in two billion years at night.

It must be daytime and it confuses your system.

So if you were to visit my house at night, it looks like a submarine.

There is red light, right?

The neighbors think I'm a vampire.

It doesn't matter.
