Do good deeds for the sheer sake of doing them - don’t dwell on the thanks you should receive.
My mother was the most charitable person I have known. Though we had very little, she would give what she could to those who were needy. All her life she gave to orphans, and there were times when we had barely played with a toy or worn an outfit when we would find it was missing only to find out she had packed it and sent the items to the orphanage in Italy. Her favorite saying was, "do good and forget about it but do something wrong and think about it." Both my children grew up to be charitable because they watched their mother, father, and grandmother give. We learned that when we give to others we give to ourselves. I have learned that those who give often get greater satisfaction than those who receive. I believe this to be very true. Just think about the holidays and how good we feel when we give. Wouldn't it be wonderful if we gave as we do on holidays like Christmas? That's my goal this year.
