We're all cool when we're dead

Speaking from personal experience, I can attest that it is preferable to live life as a person succeeding as well as he can at being the person he thinks he ought to be rather than living life as a person perpetually failing to live up to the expectations of other people.

Or, in the words of Matt Haig: "Never be cool. Never try to be cool. Never worry what the cool people think. Head for the warm people. Life is warmth. You'll be cool when you're dead."
