Gratitude is an antidote to negative emotions, a neutralizer of envy, hostility, worry, and irritation.

一句话，先是太胆小，明知错的事却不敢不做；后来也还是太胆小，明知对的事却不敢去做。

Boundaries define us. They define what is me and what is not me. A boundary shows me where I end and someone else begins, leading me to a sense of ownership.
