Get Everything Done

There's a mention about using the 5T system and a reference to Mark in yesterday's Guardian Weekend magazine. The article is called Fight The Feeling

Is it this one?

The second to last paragraph reads

"Try the five-item to-do list

One major problem with your endlessly expanding to-do list is that it fuels the fantasy of one day getting it all finished; adding one more item to the list feels effortless, so it’s dangerously easy to overcommit. The productivity coach Mark Forster proposes a radical alternative: instead of an open-ended list, use one capped at just five items, so you’re forced to complete (or consciously abandon) a task before adding another. The obvious objection to this is the risk that you’ll forget something important if you’re not allowed to write it down. But let’s be honest: you already forget important things anyway."

That's the one!
