Your entry, Tuesday evening Spent the whole day at my desk and got nothing done. I keep opening the same document and closing it again.

A letter from Seneca

My friend,

You write that the day felt wasted, that you sat at your desk and nothing moved. Yet you noticed it, and noticing is the first step back to yourself. Most people let such days pass without a glance.

A question to sit with

What would you do with one hour if no one could see the result?

Tomorrow, guard one hour as if it were the only one you owned.

Yours, Seneca
