Some believe it is only great power that can hold evil in check, but that is not what I have found. It is the small everyday deeds of ordinary folk that keep the darkness at bay. Small acts of kindness and love. Why Bilbo Baggins? Perhaps because I am afraid, and he gives me courage. – The Hobbit
At some point during their journey, Gandalf is asked why he brought Bilbo (the hobbit) along.
The lines above are his explanation.
As you go about your day today, remember that you have an opportunity through your ordinary deeds to make a difference.
Make it a great day.
