While there are many reasons for individuals to feel the need to give back to society. One feeling that is prevalent among most volunteers is "hope".
*They hope they can be up to the task at hand.
*They hope that they can positively influence the subject.
*They hope they do not harm anyone in the attempt at helping.
*They hope to make a difference.
As long as there is hope something good can be obtained. Thus, never lose hope!
