When you work with the public, it's important to get lots of private time. Solitary pursuits like reading, communing with nature and praying will be therapeutic. Even someone who loves humanity can become drained by waiting on others. When you begin to feel irritated and annoyed, take a break. Give yourself permission to do whatever you want. Your nearest and dearest can take care of themselves while you enjoy some rest and relaxation. Do you have children? Ask a neighbour or relative to babysit while you recuperate.
