Recently, I’ve stopped scheduling client work on Fridays, especially in the late afternoon. Instead, I’ve started to reserve much of the day as a ‘reset’ — a block of time to catch up on all the non-billable, non-design work that’s piled up over the week (stuff like invoicing, banking, project management, scheduling, file/resource management, writing, sales and marketing).
Condensing these tasks into a continuous block of time increases my productivity and flow, sets me up for an awesome weekend, and gives me a clean slate for next week.
