For me, I give myself a buffer. I tell myself I want to leave at said time, which normally doesn’t happen but giving myself that buffer helps. Also, I work at a major airport where we have to shuttle in from the employee parking lot.. So have to give myself another buffer to count for problems that may arise from my car to the concourse.
I give myself twice the time I think I need and I have a really dialed in routine in the morning
I can't! That's one my biggest pet peeves. I just turn off all alarms!
