What Would You Rather Suffer From...

what would you rather suffer from: thinking too much or doing too much?
I came to this question while writing my essay for my history class (should be finishing it now but I'm too distracted by my question)

Wow this question was written a long time ago when I was still in college and now I have graduated.
I want to answer this now since I don't have anything to do and it is an interesting question.

First of all, I would like to explain what I mean by thinking too much and doing too much. What I mean is that one is more on the mental aspect and the other one is more on the physical aspect.

I believe that I would rather suffer from doing too much than to suffer from thinking too much. Every time I think too much, I would get a headache and my mind just shuts down so I wouldn't be able to do anything.
