I’m Marc Zao-Sanders. I run a learning technology business (filtered.com), write, and have a slew of other responsibilities. My means of coping and even thriving through all this is by doing one thing at a time. This site is devoted to taking that approach to business and in life.

I’ve written articles about productivity, timeboxing and AI which have been published in various publications (see below). The Harvard Business Review piece on timeboxing, in particular, inspired a TikTok video which gathered over 10 million views.

Timeboxing — intentionally choosing what to do, when to do it and getting it done — is the ultimate time management technique and can help any human being achieve more while doing (and stressing) much less. I’ve written a book on the subject, published by Penguin Random House, published in 2024 in the UK and coming out in 33 languages around the world soon after. It seems to have struck a nerve.

If any of this interests you, please sign up to my newsletter, called One Thing at a Time, which goes out every Wednesday.
