I wanted to pull this quote out of the previous post and state it by itself. It's incredibly powerful, and it's a tenet by which I've lived my life for a very long time, even though I had never heard the quote.
“I beg you—do something to justify your existence, something that gives you the right to be dressed in your skin…because it would be too senseless after all, for so many to have died while you live doing nothing with your life.”
