Happiness is a good flow of life； the conviction that you are taking part in the universe's purpose.
You know what it’s like to wake up in the middle of the night with a vivid dream? And you know that if you don’t have a pencil and pad by the bed, it will be completely gone by the next morning. Sometimes it’s important to wake up and stop dreaming. When a really great dream shows up, grab it.
我們的心靈不安，直到在你里面找到寧靜。
