What needs to be done to enjoy life sometimes.
There's a lot of bad stuff going on all the time.
Genocide, poverty, sickness, starvation, war, torture, Dopey.*
It can be a downer to think about it all, so just do what you can to fight it or at least avoid contributing to it (donate money and food, don't get people sick, heal them if you can, don't torture or genocide people, you know, whatever you can manage), but then try not to let it bog you down.
