Stop striving for perfection! You'll drive yourself crazy, you won't be able to stop and you won't enjoy being in the moment. A better goal is to aim to be happy instead of perfect. Perfection is overrated. If you ever attain it, you'll realize how empty it feels.
Kindness emerges from someone who's confident, compassionate and comfortable with themselves. A kind person is loving and giving out of the goodness of their heart. At the root of extreme niceness, however, are feelings of inadequacy and the need to get approval and validation from others.
