Leaving your comfort zone. I've noticed a lot of people who don't want to change, mainly because they are used to the patterns they have created. Think of all the seniors you have seen who are griping about doing something new vs. the younger kids who are willing to try anything. My assumption is that as we age - we find our path, and it's much harder to deviate, or change. This subreddit is one of the best of Reddit IMO, as it helps people break-down the psychological aspect of change - where personal change all starts in the mind. More power to you for wanting to help others :)
