心理学唯一有效的数据是可观察的行为。
The quality of an organization's products and services is a direct reflection of the quality of its management.
I don't think about genres. I just make music that feels good to me.
I'm not afraid to take a stand. Everybody come take my hand. We'll walk this road together, through the storm.
质量不是问题;它是一个解决方案。
