Self-employment is rough. One day you’re sleeping in for an extra half hour, and the next you’re staying up until 5am and realizing you haven’t seen any of your friends (or the sun) in months.
Dust and dirty dishes start to pile up. You neglect the laundry. The laundry moves in with someone else. Nothing is ever open when you’re awake and you slowly succumb to preventable diseases.
