Learning is essentially a matter of stimulus-response connections.

我不需要理由去毫无歉意地做自己。

"Die Wahrheit liegt oft in den kleinen Details verborgen."

死亡可能是人类最伟大的福气。

I am tomorrow, or some future day, what I establish today. I am today what I established yesterday or some previous day.

每一个挑战都是学习和成长的机会。
