Happiness. That's all I can say for now.
Not just for me but for my family, friends and everyone else in the world.
I don't know what I can do to get the most happiness out of life long-term but hopefully I'll find out soon!
To be honest I don't value my life that highly. I would die to save the life of, well, anyone really. Part of me hopes I get that opportunity, to give someone an entire lifetime worth of happiness. That would be something to have lived for.
