Quality is free. It's not a gift, but it is free. What costs money are the unquality things -- all the actions that involve not doing jobs right the first time.
质量是免费的。它不是礼物，但它是免费的。花钱的是那些不质量的东西——所有那些没有第一次就把工作做好的行为。
"The world is full of wonders, but they become more wonderful when we share them."
The more you know about yourself, the more patience you have for what you see in others.
"The hardest thing in life is to know which bridge to cross and which to burn."
每个数学问题都有解决方案，但并非每个解决方案都显而易见。
The more you look, the more you see.
I don't let negativity steal my joy.
