There are a wide variety of ways to communicate remotely, from phone calls to emails to applications like Skype and Zoom. The use of these can be very helpful when keeping contact between mentors and mentees. I think regularly scheduled meetings are useful, but one of the things I have appreciated most from my mentors is when they reach out to me unprompted to check-in. Just a quick check-in on how I am doing, both mentally and professionally, makes me feel the full strength of my professional network.
Are you a mentor to anyone in your life? Is there someone who could benefit from you reaching out to them during these isolating times?
