Why do YOU volunteer?

Why do people volunteer?
I know why I do, but why do you?

I ask because of a growing frustration with other volunteers. Not all of them. Many are committed and hard working and accept the responsibility of the tasks they take on completely. Then there are some that take on tasks that directly affect the work of others, and do not follow through. The excuses range from "I have a full time job" (so why did you take on something that would conflict with that), to blaming others or just simply not completing the tasks needed. Some people volunteer for the ego trip of "doing something good", some get caught up in their own importance. Some get so impressed with themselves and their role that the only way to stop them from doing real damage is to fire them.

I am frustrated with a board Treasurer who has run amok with power. She took over some tasks when the director was fired, she micromanaged way too many things, but she was a part of keeping the agency open. However there is a new director, and she refuses to let go and just do her job. She has taken vital documents to her home and makes excuses about the fact that she has not turned them back over while she dallies with the information needed to complete the previous year's audit. We are uncovering the poorly managed bits that she did take over (bit by bit). ARG.

She is making me crazy.
