Question 2: Is bravery an essential ingredient for a happy or fulfilling life? Can someone live a good life without ever having to be particularly brave? Why or why not?

One can be happy but can not be fulfilling without bravery.  Because the absence of bravery is the absence of possibility. 

Question 3: What is one thing you would like to be braver about in the future? It could be speaking up in a meeting, trying a new hobby, or having a difficult conversation. Share your goal with the group for encouragement!

Having a difficult conversation,  and don't cringe other's whispers and criticisms. 

I'll go school tomorrow but I stay up late tonight.  Is it a action of bravery :)
