The past is a shadow that follows us, but the future is a light that guides us.

No wise pilot, no matter how great his talent and experience, fails to use a checklist.

"It's not generally realized that all writers, even the greatest, are also readers first and last."

Optimism is not just a trait; it's a skill that can be cultivated.

"The heart has reasons that reason does not understand."

能够知足的人，上天不会让他陷于贫寒；能够忍辱的人，上天不会让他遭受灾祸；能够无欲无求的人，上天不会让他沦于卑贱；能够放浪形骸之外的人，上天不会让他困病；能够不贪生怕死的人，上天不会让他死去；能够随遇而安的人，上天不会让他坎坷困顿；能够造就人材的人，上天不会让他一生孤苦；能够用生命造福天下后世的人，上天不会让他失去后嗣。
