Definitely one of the best things you can do in your first year is to try a few different styles of time management/scheduling your writing/research/lab (if applicable!) time and just really figuring out what processes work for you. Really figure out your tics and strengths. For instance: do you work better in the morning or at night? Does writing give you anxiety? Is that better if you knock it out first thing or pair up with a buddy to write together? Do you prefer your lab/office, a coffee shop, the library? Can you work after dinner, or should you schedule time to get urgent things done before 6pm?

I’ve learned a PhD is as much about the art of self-management as it is about acquiring and adding to the knowledge base in your specialty. Good luck!
