I think what Andrew means by "totally stupid" is that by calling yourself "totally stupid", you are free to do what you want without caring for other people's opinions. You are totally stupid and you don't care. The final part of the song is the same message but presented differently. Andrew says that "when we look into the future to the place we haven't gone", and "see what we haven't done", we will regret it deeply, so we should live life to it's fullest everyday and when that "future" comes, we will not regret a thing. That's just my opinion.
