Every barrel we produce must be done responsibly, with full consideration of environmental and social impacts.
Life is a series of choices, and the hardest ones are the ones that matter.
对于世界而言，你是一个人；但是对于某个人，你是他的整个世界。
The whole is other than the sum of the parts.
The only limit to our realization of tomorrow will be our doubts of today.
