That being said you should be careful about who or what you give your money to. Find a cause you believe in but make sure the people "leading" that cause are taking care of the money they are given. When we donate to a charity outside of our normal giving, my wife and I give to the Salvation Army. We do so because we believe in their mission and because they are one of the most efficient charities year in and year out. I know this because they are very transparent with their financial accounting and have gained this reputation through years and years of good stewardship.

If you are looking at giving to a charity but are not sure whether they are the best investment for your giving check out give.org and charitynavigator.org. I prefer give.org because they include the financial information from religious organizations in their data, but both are great websites. This is a great way to make sure the money you give is actually going to the cause or causes you believe in.
