Check Instagram. Check TikTok. Open WhatsApp, to see if you have any messages which your phone has neglected to tell you about. Check Instagram. Have a shower. Have a shave. Make lunch. Post about your lunch on Instagram. Treat yourself to an hour long episode of something whilst you eat. Let your lunch go down, scroll through TikTok. Make a to-do list. Make a bucket list. Invent a new life for yourself because nothing should be this hard. Scale back that new life based on budget. Have a shower to wash away the shame of your cowardly moment. Sit in your towel for half hour. Air drying is better for the environment.
Notice the time.
Get back to your desk.
Fuelled by the fact that there is simply no other conceivable route forward: write.
