I said I'm trying but my body hasn't cooperated with this start time for the last 30 years, I don't see why it will start now.

For the last 5 years I've been starting at 9:30 and finishing at 6. And I haven't been late due to me as a person since.
Public transport problems happen occasionally, but it was that simple for them to get a full day out of me reliably.
