Productivity Advice

If boredom is a necessary ingredient, then portable internet is a disaster for doing the work.

Startups don't get built by watching startup advice videos on YouTube. They get built by doing the work. All you need is a laptop and a metrocard.

More tools give you negative utility. They won't make the work go faster. But they will consume as much time as you are willing to waste.

Do the work.  That's all the productivity advice you need, and the only useful productivity advice you're ever going to get.
