Where do YOU get YOUR meaning? This is something we as human beings all have to decide. What is your purpose in life? If you don't know your purpose, stop whatever you're doing. This is the most important decision of your life, because it determines everything that you do. Lock yourself in a room with no distractions, just a pad of paper and a pen. Start writing. Don't leave the room until you have defined a clear purpose for your life.
My purpose is this: to reduce as much human suffering as I possibly can, in any way that I can. How will I accomplish that? For now, my plan is writing, but I'm willing to stay flexible. I love people so much, this is the only purpose I could ever imagine. That's my purpose. You need to find your own.
