They know how to turn off aspects of their life long enough to recharge through other means, healthy means. They also don't get quite as overwhelmed to the depth and breadth that those of us with complicating mental health issues do. I know my unhealthy thinking patterns magnify what is going on and allow things to get out of control, whereas a healthier individual is more able to handle issues as they come individually instead of having them pile on each other and become a huge mountain to climb. I'm getting better at managing life as it hits me and managing my thinking mor rationally than I used to rather than things getting out of hand, but it is something I have to work at every day. That kind of skill just comes more instinctively and naturally to some people.
