Every pursuit of a dream is a journey of the heartstrings. You feel the pull of your dreams, sometimes painfully, but you keep going because you know that the music they make when achieved is worth every note.
Don't always think "it's still in time in the future". One day you will find that for some people and some things, it really will be too late.
No matter how hot the water is, it will still cool down; no matter how full the enthusiasm is, it will still fade away; the person you love the most may still leave, so get used to people leaving and the tea getting cold.
Liveliness is merely a short-lived consumable, while it is loneliness itself that sustains your life.
