I plan my days backwards. If my appointment is at 13:00 tomorrow I check the travel timetables and determine the absolute latest I have to leave. From there, how long does it take to get ready? What time do I have to be awake in order to get ready? What time do I have to be asleep by in order to get a full night of rest? The anxiety and restlessness makes sure I stay on top of it.
...and a lot of weed to make sure I actually do fall asleep on time as one or two puffs too many puts me in the right spot to fall asleep quickly.
Tests? Pfffft. I am the test.
