The Ultimate Productivity System Built Around 'Design' and 'Intention'

The ideal work day, recommended by neuroscientist Andrew Huberman, is one where you schedule your cognitively demanding work in 90 minutes blocks.

This recommendation is based on ultradian rhythms, which are natural cycles of approximately 90 minutes that exist in all of us. Our nervous systems go through these all day and all night, and biologically we are optimized to work and focus in these 90-minute blocks.

The average person can do 1–3 of these deep focus work bouts per day. It depends on how well you’ve slept and are nourished, and how trained your focus capacity is.

So, I’ve been using color coding in my calendar to ensure I’m balancing ‘focused bouts of work’ with ‘mind-wandering breaks.’

• 🔵 = personal tasks • 🟣 = work • 🟡 = exercise + tasks that require movement like cleaning, groceries,.. • 🟢 = writing, reading
