genuine question about first year PhD workload

hey everyone. i was recently admitted to a couple phd programs this upcoming fall. i’m genuinely so excited but also nervous and having second thoughts about the workload of the program, especially the first year. for those who have been or are in an Econ PhD program, how did you manage your study and work time with your life? i have seen (here and in other social media platforms so not necessarily the best sources) that sometimes people study/work 70-80+ hours per week and this is something i’m honestly not willing to go through. i’d like to still have time to go to the gym, spend quality time with my partner, maybe go out to dinner with friends on a friday night. i’m willing to put in the hard work of course that a phd requires, but i don’t want it to be all consuming. i know during quals, midterms and finals it can get brutal (and that’s okay and normal) but im talking about regular weeks, were you able to have a life outside your phd?

keep in mind im NOT going to a T10 or even T30 program, im going to a ~T70 school, if that changes anything.

i also know that talking to students in my specific department is the most useful tool, and I am doing that but also wanted to hear some other experiences.

tldr: how was your work life balance during your econ phd? especially the first year.
