I think and think and cannot cease from thinking.

我想了又想，一直想个没完。

I think and think for months and years.

我一直在反复思考，月复一月，年复一年。

Think, think and think. You think; therefore, you are.

思考思考再思考。你思故你在。

Take walks and think and think until you come up with original insights to write about.

出去走走，认真的想想，然后再想想，直到你有了原创的观点可以写。

A person and do and check, and think and think and, not that you now in where, but in your heart to go away.

一个人且行且止，且思且想，不在于你现在在何处，而在于你心所往的远方。
