Remember that you don't always know the good you do. During the 19th century, political figure and diplomat Charles Francis Adams kept a diary. One day he entered:
"Went fishing with my son today - a day wasted." His son, Brook Adams, also kept a diary, which is still in existence. On that same day, Brook Adams made this entry: "Went fishing with my father--the most wonderful day of my life!" The father thought he was wasting his time while fishing with his son, but his son saw it as an investment of time.
Don't underestimate the ways that the ordinary actions of your life may be used to touch others.
