I never realize how much rest I don't get / didn't have until it's too late. Going through the motions of adapting to a new city and job takes a lot of energy. Mix that with a must do/see all mentality isn't helpful either.
Being overworked can be painful and ultimately unproductive...and in my case, physically draining. I've overworked my capacities to the point that I'm causing my body to breakdown. (Hello Emergen-C).
Take time to give yourself rest to clear your thoughts and let your mind and body recover from the hard work you've put in.
Reminder: I am not invincible.
Neither are you.
