Been a long time coming, but I ran into a couple of videos recently that I thought would be interesting.
First this one with a reminder that what you make doesn't have to be awesome, it just needs to exist.
Second, and a bit longer, but totally worth it is this one about allowing yourself to be bored.
Yes, both of these would take half an hour of your time, but I think it's worth it for students to see them - even if it isn't directly about drawing and painting. In the end I would suggest it's pretty good life advice.
