When I was the most anxious in my life, I developed a great strategy for being on time. See, if I were to have an appointment, I'd Google maps it. If it's 22 mins away I am calling that 30 mins. So if my appt is at 2, I should leave at 130. But, if there's traffic, or no easy parking or something... gotta pad it. Alarm set for 1:22.

Ok so a sane person knows I'm gonna be like 15 mins early.

So I arrive 20 mins early. Okay perfect. Set a timer for 9 minutes. Walk. In any direction. Until the timer goes off. Then abruptly turn around. Arrive gracefully about 1 minutes early.
