The Art of Giving
There are non-profit foundations that need marketing and content, but do not have the funds to hire an outside creative agency. Volunteers then play a critical role.
I've discovered that volunteerism works and here's some of my examples. It isn't an exact science. I've been a volunteer judge for the American Kennel Club for more than a decade, and when I started with the AKC I figured it would last six months. Not 14 years!
However, they'll be times when volunteering does not work for you, so before you agree to donate your talents, ask the important questions regarding what's expected of you.
Volunteerism needs to be a win-win situation for all parties concerned, and you should not have it any other way.
