The classic response of an introvert to growing problems in the world is to become a recluse. Not saying you are an introvert, but it's a common response. The best thing to do is the opposite: Go out and live as the kind of nice, unselfish, non-greedy, proactive person that you wish other people to be. Thereby doing so, you will provide a little bit of sunshine to make the world a better place, and you'll subtly influence other people to be the same. You may feel like one tiny piece in the puzzle, but 1000 piece puzzles still require each individual piece to complete. Don't retreat. Face your fears: Be the driving force for good, not the one that's forced. May you be blessed in this!
