If I was to look at what are you watching, reading, what are you listening to, what are you consuming information-wise, who are you surrounding yourself with... If I could have access to those things, I could make a pretty good prediction about what your attitude is, what your activities are and how you feel about things and what are the results that you're getting.

If you are unhappy with the results or with the output of anything, change your inputs.

If you want better outputs, take a look at your inputs.
