If you want your life to stand for peace and kindness, it’s helpful to do kind, peaceful things. One of my  16 ways to do this is by developing my own 17 actions. These little acts of kindness are  18  to be of service and reminders of how good it feels to be  19  and helpful.
We live in a rural area of the San Francisco Bay Area. Most of what we see is beauty and 20  .One of the exceptions to the beauty is the  21 that some people throw out of their windows as they are  22 on the rural roads. One of the few drawbacks to  23  the mountainous area is that public services, such as litter collection, are less  24  than those are closer to the city.
   A helping action that I practice  25  with my two children is picking up litter in our surrounding area. We' ve become so  26  to doing this that my daughters will often say to me in exciting  27 , "There' s some litter, Daddy, stop the  28  !" And if we have time, we will often pull over and pick it up. It may seem  29  , but we actually enjoy it. We pick up litter in parks, on sidewalks, practically  30 . Once I even saw a complete stranger picking up litter close to  31  we live. He smiled at me and said, "I saw you doing it, and it seemed like a good       32 ."
Picking up litter is only one of an  33  supply of possible helping actions. You might like holding a door open for people,  34  lonely elderly people in nursing homes, or removing snow off someone else' s driveway. Perhaps you might  35  something that seems effortless yet helpful. It' s fun, personally rewarding, and setting a good example. Everyone wins.
