Adapt Oneself in Chinese / Japanese...

應變 means “to meet a contingency,” “to adapt oneself to changes,” or “to adapt to changes” in Chinese.

It's also used in Japanese but usually only in the context of Buddhism. 應變 is probably the shortest way to express the idea of adapting and overcoming whatever circumstances present themselves.

応変能力 is “the ability to take proper steps to meet the situation,” “the ability to adapt oneself to the requirement of the moment,” “the ability to adapt to circumstances,” or “adapt and overcome,” in Japanese Kanji.
