One example for me is the time I told my formation director that I was struggling with the anxieties of ministry and community life. So he said:
The poor man is perpetually anxious.
That really stuck with me, and it reminds me that a true vow of poverty commits me to a life that will be anxious at times. And it also reminds me to be humble, because my anxiety is as nothing next to the struggles of those who are the real poor of this world.
