Mine is partly opportunistic: if a rally is announced, can I reasonably get to it, and can I tolerate being outside that long? (The latter is based on a combination of the weather and how I'm feeling that day.)

This may not be the best approach, but it's what I'm doing now.

Also, keep in mind that some of what we're already doing counts: I was talking to my mother yesterday, and she was saying that she wished she had the energy for phone calls or rallies. I reminded her that she is doing important political work that very few other people can: Holocaust education, telling people about her personal experiences as a survivor. She has been doing that work for a long time, and plans her schedule around it, but wasn't thinking of it as political/resistance work.
