I woke up 15 minutes before the train I was planning to take. I decided to take a shower instead of rush out the door. It still gets me to the airport about two hours before my flight, so I'm good. Very glad I only have my check-in.
Keeping cool, albeit only in attitude, and adjusting as need be. It's nice to know I've gotten better about this kind of thing. It used to send me into a panic when things didn't go as planned, but I've gotten better at letting go, assessing the situation and figuring out the next step.
And the next step is just to get on the next train. Which has arrived.
