世界上最好和最美丽的东西是看不见甚至摸不着的——它们必须用心去感受。
"The best and most beautiful things in the world cannot be seen or even touched - they must be felt with the heart."
"The advantage of poetry over life is that poetry, if it is sharp enough, may last."
I don't think you can ever do your best. Doing your best is a process of trying to do your best.
