This is my number one piece of advice for doc students! I've been able to have genuine conversations with so many wonderful scholars by emailing them questions about papers I love.

You can do this right now:
Think of a person who wrote a paper you love, whose work influenced or helped you, or has made your professional life better.
Search up their email address. Shoot them a quick email of thanks. It means so, so much. This is a rough time of year, share some joy.
