Reddit featured a man who is 23 in late stage kidney cancer who doesn't plan on seeing his 24th birthday. A woman who was on the site started a fund for him to travel the world and strangers donated over $30,000 and multiple other gifts and experiences around the world.
I'm having trouble imbedding the link so i'll just post it for you to watch the video. It's definitely worth watching for 3.5 mins.
This video and others have really got me thinking about how really great my life is. Yesterday's feeling of gratitude has definitely carried over into today and inspired me to do something great for someone. Have you ever helped or been helped by a complete stranger?
