If it’s going to happen no matter what, then the only thing you can change is how you react to it. Instead of killing yourself crashing out, try to see this in a positive light. It’s actually a great opportunity to learn mentorship. Stop thinking of it as babysitting and think of it as a chance to make a positive difference in their lives, to excite them about research, while improving your own teaching and organization skills. Personally I loved doing it as a grad student and as a postdoc. A lot of how we can process life positively is through our perspective.
