I make my own meanings. If I work hard on a chapter of my book, it means I'm closer to finishing and being able to share it. If I listen to one of my favorite bands, it means I've been able to enjoy listening to one of my favorite bands. If I read an interesting article about, say, the decriminalizing of drugs in Portugal, it means I've learned something new. If I volunteer at a homeless shelter, it means I've helped people.
Simple, really.
