Doing good deeds can be a messy business; far messier than seems necessary.
Some people won’t appreciate your kindness.
Some people will be oblivious to your efforts and not even notice your actions.
Some people will attempt to take advantage of your generosity.
Some people will be rude to you or complain about your good deeds to others.
There will be times when you feel inadequate to make a difference when the challenges are so great.
