When I picked up Hello Sleep by Jade Wu, I figured it’d be a quick read.

You know the usual advice: get 8 hours, avoid screens, don’t drink coffee too late.

So I expected, at most, a light refresher to help me optimise a few things here and there.

But the book went beyond those “hacks.”

In fact, the book challenged some of my assumptions about sleep. For example:

Not everyone needs 7 to 8 hours of sleep.

Some people genuinely do fine with less.

And those sleep cycle charts we’ve all seen…those are the worst.

Trying to time your sleep into neat little 90-minute blocks is useless.

As useless as smashing the elevator button, thinking it’ll make the lift arrive faster.

It feels like you’re doing something useful. But it makes no difference.

(So if you wake up feeling refreshed even though your WHOOP or Apple Watch says otherwise…trust yourself instead.)

I’m only partway through the book, and I’m already eager to find out what else I’ve been wrong about.

It’s a good reminder: sometimes, it’s worth revisiting topics you think you’ve already mastered.

In fact, it’s even better when you come in thinking you know it all.

I’ve always believed a good book should feel like a two-way conversation.

You and the author, sitting across the table, trading ideas.

And with each reread, you bring new context to the page: more life experience, more perspective.

It’s the same when it comes to writing content.

Most of what we write, especially in email, isn’t brand new.

But when you return to a familiar idea with a fresh lens, layer in your voice, and meet readers where they are today…

They get to read stuff that feels new to them.

Do that enough times and you’ll be positioned as someone who always has the insights, or the writer who never runs out of ideas.
