It's funny. No matter how hard you try, you can't close your heart forever. And the minute you open it up, you never know what's going to come in. But when it does, you just have to go for it! Because if you don't, there's not point in being here.
Everyone has a sense of humor. If you don't laugh at jokes, you probably laugh at opinions.
To be a philosopher, just reverse everything you have ever been told...and have a sense of humor doing it.
