Kurt Vonnegut: Be soft. Do not let the world make you hard. Do not let the pain make you hate. Do not let the bitterness steal your sweetness. Take pride that even though the rest of the world may disagree, you still believe it to be a beautiful place.
Regret nothing. OK, well. wait a second. except perhaps, that time when. No, this is good advice. No regrets make tomorrow a better day. Unless you just woke up and need to accept that today is tomorrow. Come on better day!
