I think the most important thing in life is to be happy.

Be a pro. Back up your back up. Have at least one physical backup and one backup in the cloud. Have more than one of each. How much would you pay to retrieve all your data， photos， notes， if you lost them？ Backups are cheap compared to regrets.

生命虽短，却很宽广。

我们必须记住，历史是由胜利者书写的，但记忆却是由失败者保存的。

对世界抱有理想化的看法是错误的。这就是麻烦的开始。这就是一切开始瓦解的地方。
