You do not need to change people. Simply pull back the curtain obscuring their view of the truth and let them stare. Common sense, compassion and kindness will take it from there.
Cancer gave me an understanding of the point of all this. To survive. Most of our lives it is easy but for the moments when it becomes difficult, when accident or sickness or sadness strikes, it's just about remembering one thing. You must simply survive.
You need to spend time crawling alone through shadows to truly appreciate what it is to stand in the sun.
