HAPPY BIRTHDAY GUVNOR!
Is it not more appropriate to let life ask you about meaning rather than worrying yourself over life’s meaning? After all some would argue that it is a mystery to be lived rather than a problem to be solved!
Very few people have the ability to base their optimistic ideals in reality. You pull this off rather well Mr Senn, and I have no doubt that you will be able to get out of life whatever it is you dedicate yourself to. Keep living the dream!
