So I've been a big believer of this since I was an undergrad.

Like you give your time a job as opposed to having a list, which is somewhat orthogonal to what's actually happening in your day.

And then just as you go through your day saying, what do I want to try to do next, which I think is a lot less efficient.

Yeah, more or less.

That's my cutoff.

Now, the one exception is if I'm writing on deadline, I'll sometimes – like if I need to get more writing done, I can do an evening writing session, which I got used to through long experience.

I used to write my blog post at night after like my kids went to bed.

Now they're older and they don't go to bed as early.

So it's like the one thing I have left.

That I'll do after 5.30.

It's like every once in a while I'll do like a 90-minute evening writing block.

But I call this, by the way, this whole philosophy, I call fixed schedule productivity.

I've been doing it since I was a grad student.

Fix the work hour schedule.

That's my commitment.

I work in these hours.

And then work downstream from that for everything else.

So like this controls like even what you decide to bring into your life because you know I can't go past a schedule.

And it drives you to be more innovative in how you deal with your time and schedule.

You have to be efficient because you only have these hours here.
