Some good suggestions here.
The main heading are:
* It doesn't have to be a huge event.
* Search out other perspectives.
* Use listening as its own form of activism.
* Tell stories with empathy.
* Understand the world to understand what's happening at home.
* It's not about you.
* Get over feeling you have to be perfect and know everything.
Any suggestions from those of you who were active in the past (60's and 70's for example)?
