Inform yourself about animal issues, and listen to different perspectives on how to help animals. Don't latch onto the first opinion that you hear about what is the most urgent issue, or the best way to help animals. Read everything you can on the issues, and be critical when presented with facts. Take an honest look at what your talents, strengths, and passions are, and determine how they can be used to the greatest effect. Once you've informed yourself, do your own thinking. The best way for you to make a difference might not be obvious, and might be something that no one has thought of yet.
