What should I focus on before starting my first TT job?

I defended my dissertation in early March, submitted all the revisions, and signed a contract to start my dream TT job at an R1 this Fall! Now that the dissertation and job market madness is finally over, I suddenly have so much time on my hands. I’ve already started working on turning my dissertation into publications, drafting a few papers—but I’m wondering what else I should be doing between now and the start of the semester. I’ll be prepping for my Fall courses, of course, but beyond that, I’m not sure how to best use this in-between time.

Any advice for a brand-new, incoming TT assistant professor in the social sciences? Should I focus on professional development? Try to get as many papers ready for submission as possible before the tenure clock starts? Work on personal growth or just take a breather?

Would love to hear how others approached this transitional period!
