You don't have any hatred in your heart. When its sunny the sun is bright and shining. When its gloomy the weather is a nice overcast. Stress doesn't matter since the only truly important thing is love anyways, it makes everything else seem trivial. You always have drive since you are doing if to protect that thing which is most important, love.
Its warm, it makes you laugh, it makes you annoyed, it can even make you cry and you love every moment of it. You can't live without it
Its not selfish either.
